chore(release): bump workspace version to 0.8.0

The [workspace.package] version (inherited by every crate via version.workspace)
is the release being cut; refresh the 9 workspace entries in Cargo.lock to match
(CI builds --locked). Canary derives from the tag (scripts/ci/pf-version.sh), so
cutting v0.8.0 auto-advances canary to 0.9.0.

+    unit-tested. `manual_position` helper for a single backend-local apply.
+  - **Registry group model** (Linux): group = backend (one desktop per compositor session); the
+    `/display/state` snapshot groups entries, orders by acquire (gen), and computes each member's
+    `position` via the engine. `DisplayInfo` now carries `group` / `display_index` / `position` /
+    `identity_slot` / `topology`. The backend reports its resolved slot via the new
+    `VirtualDisplay::last_identity_slot` (KWin only), so the arrangement + state key on per-client identity.
+  - **`PUT /api/v1/display/layout`**: persists the console's manual arrangement (positions keyed by
+    identity slot) via the pure `EffectivePolicy::with_manual_layout` transform (locks the current
+    effective behavior into explicit `Custom` fields + sets a manual layout — arranging is orthogonal to
+    the other axes). OpenAPI regenerated.
+  - **Registry-driven position apply** (`VirtualDisplay::apply_position(x, y)`, default no-op; KWin
+    implements it via `kscreen-doctor output.<n>.position.<x>,<y>`): the registry owns the group, so
+    right after `create` it computes the new display's position over the whole group via the pure
+    `position_for_new` (existing same-backend members in acquire order + the new one appended last →
+    `layout::arrange` → the new member's placement) and calls `apply_position`. This makes **both**
+    auto-row (deterministic left-to-right, not just the compositor's default) **and** manual placement
+    go through one seam. Guarded: the registry skips the desktop origin `(0, 0)`, so a single-display /
+    first-of-group session (and every non-KWin backend, which no-ops `apply_position`) issues no
+    positioning at all — the historical single-display path is byte-for-byte unchanged. `position_for_new`
+    is unit-tested. *On-glass-validation-pending (kscreen positioning of a live virtual output).*
+  - **Per-group topology restore** (design §6.1 — restore the physical only when the group's LAST member
+    drops): the KWin `exclusive` restore no longer rides the per-session `StopGuard` (which would re-enable
+    the physical the moment the FIRST of several exclusive sessions dropped, under a live sibling). KWin
+    now hands the restore to the registry as a closure (`take_topology_restore`); the registry keeps it in
+    the display **group** (`Entry::topology_restore`) and, on teardown, **floats** it to a surviving
+    same-group sibling (`hand_off_restore`) or, when the group empties, runs it — outside the lock, BEFORE
+    the last output's keepalive drops, so the compositor never sees zero outputs. All three teardown paths
+    (lease drop / linger expiry / mgmt release) honor it. The single-display path is byte-for-byte
+    unchanged (one member → run on its teardown). `hand_off_restore` is unit-tested (float / run-on-last /

+    auto-rowed against, topology-grouped with, or restore-grouped with another gamescope. Unit-tested.
+    (§6B single-output "decline extras" is Stage 6.)
+  - **Console arrangement table (web)** [DONE ✓]: a `DisplayArrangement` x/y editor in the `Virtual
+    displays` card (`web/src/sections/Host/DisplayCard.tsx`) — for a ≥2-display group it renders an x/y
+    table over the live displays that carry an identity slot, seeded from `/display/state`, and Save

+    i18n; the stale `display_pending_note` copy refreshed. tsc + vite build green. (Drag mini-map is a
+    later stretch.)
+  **Remaining Stage 5 — hardware-gated residuals only (no more host/web build work):**
+  - **On-glass validation — mostly DONE (2026-07-05, KWin `.116` + Mutter `.21`):** the group model,
+    per-member positions, identity keying, group-aware `exclusive`/`extend` coexistence (a 2nd session
+    does NOT clobber the 1st's output), and **2 concurrent Mutter `RecordVirtual` monitors** are all
+    confirmed live; the keep-alive reconnect path (reuse, quit-skip-linger, tunable idle) was validated
+    deterministically with the probe. **STILL PENDING: the per-group physical-restore EFFECT** — both
+    boxes are headless so `also_disabled=[]` (nothing to disable → nothing to restore); seeing
+    `exclusive` black out a real monitor and the group restore re-enable it only after the LAST member
+    drops needs a **monitor-attached Linux box**. The group-restore LOGIC (`hand_off_restore`) is
+    unit-tested; only the physical effect is unobserved.
+  - **wlroots group-aware exclusive** stays deferred: wlroots `exclusive` is not implemented at all (needs
+    a Sway box), so there is no topology to make group-aware yet. §6A multi-view on wlroots already works
+    (independent `HEADLESS-N` outputs).
+  - **Mutter `APPLY_TEMPORARY` disconnect-revert** (§7): when the FIRST Mutter session leaves under a live
+    sibling, Mutter reverts the topology — a full fix needs a group-owned `DisplayConfig` connection.
 - **Stage 6 — §6B protocol + Linux host + GTK client.** `VIDEO_CAP_MULTI_DISPLAY`, control-

-## 5. Connect a client
+## 5. Open the firewall (if you have one)
+
+**Stock Arch ships no firewall** — every port is already open, so you can skip this. But **CachyOS
+enables `ufw` by default** (firewalld is not installed), and some other spins (e.g. EndeavourOS)
+enable **`firewalld`** — an Arch package never opens ports for you, so on those the host is
+unreachable until you allow it.
+
+The `punktfunk-host` package installs openers for **both**, so it's a one-liner whichever you run:
+
+```sh
+# ufw — CachyOS (and Ubuntu, once you enable ufw):
+sudo ufw allow punktfunk-native        # the secure native host (the default)
+sudo ufw allow punktfunk-gamestream    # …also this if you run `serve --gamestream` (Moonlight)
+
+# firewalld — Fedora-like spins (EndeavourOS, …):
+sudo firewall-cmd --reload                                    # load the installed definition
+sudo firewall-cmd --permanent --add-service=punktfunk-native
+sudo firewall-cmd --reload
+```
+
+`punktfunk-native` opens the QUIC control port (UDP 9777) + mDNS discovery; add
+`punktfunk-gamestream` as well if you run `serve --gamestream` (the fixed Moonlight ports + mDNS).
+The media **data plane** uses an *ephemeral* UDP port that the client opens with a hole-punch — the
+host streams back out through the path the client opened, so there's **nothing fixed to open** as
+long as the firewall allows outbound UDP (the default for both ufw and firewalld).
+
+Enabled the **web console** (`punktfunk-web`, above) and want to reach it from your phone or another
+machine? It's not opened by the streaming rules — open its port too, the same one-liner way:
+
+```sh
+sudo ufw allow punktfunk-web                                                            # ufw
+sudo firewall-cmd --permanent --add-service=punktfunk-web && sudo firewall-cmd --reload  # firewalld
+```
+
+That opens **TCP 47992** (HTTPS, login-gated). The mgmt API (47990) stays loopback-only and is never
+opened. Full port lists (`nftables`, explicit ports) are in
+[`packaging/arch/README.md`](https://git.unom.io/unom/punktfunk/src/branch/main/packaging/arch/README.md#firewall).

+- A firewall on the host can block it. The native protocol's **control plane** is a fixed UDP port,
+  **9777** — open this one. The per-session **data plane** rides a *separate, random* UDP port and
+  usually needs **no** firewall rule (see [Video is slow to start, or fails across
+  subnets](#video-is-slow-to-start-or-fails-across-subnets) for why, and the one case where opening it
+  helps). GameStream/Moonlight (only with `--gamestream`) uses TCP **47984/47989/48010** + UDP
+  **47998–48010** (video/FEC 47998, ENet control 47999, audio 48000) + mDNS UDP **5353**. Allow those
+  on the host's firewall.
+
+## Video is slow to start, or fails across subnets
+
+The native **data plane** (the raw UDP that carries video, separate from the 9777 control plane) uses
+a **random, per-session UDP port** — the host binds `0.0.0.0:0`, then tells the client which port it
+got during the connect handshake. There is no fixed data port.
+
+Video flows host → client, but the **client sends the first packet**: a small *hole-punch* datagram to
+that port. This is deliberate. It lets the host learn the client's real (possibly NAT-translated)
+source address and stream back to it, so a session can cross a NAT or a stateful inter-VLAN firewall
+**without** a forwarded data port. What it means for a host firewall:
+
+- **Same LAN, no host firewall (or the port allowed):** the punch arrives immediately and video starts
+  at once. Nothing to configure.
+- **Same LAN, host firewall that denies inbound** (ufw/nftables/firewalld default): the punch is
+  dropped, so the host waits **~2.5 s**, then falls back to the address the client reported and streams
+  anyway — a stateful firewall admits the return traffic because the host sent first. **Net effect: it
+  works, but each session takes ~2.5 s longer to start.** That slow start is the symptom of a
+  data-plane rule you're missing.
+- **Across subnets / NAT:** the same punch-then-fallback applies, as long as the host's outbound video
+  can reach the client (the path's stateful firewall then admits the return). If the host itself is
+  behind NAT reached only via a forwarded control port, the data path may not establish — this is the
+  case a fixed, forwardable data port would solve.
+
+To remove the ~2.5 s fallback delay, **pin the data port** with `--data-port` (or the
+`PUNKTFUNK_DATA_PORT` env in `host.env`) and open exactly that one port. The host then binds that
+fixed port, skips the punch-wait, and streams straight to the client — no timeout to pay:
+
+```sh
+punktfunk-host serve --data-port 9778     # or PUNKTFUNK_DATA_PORT=9778 in host.env
+sudo ufw allow 9778/udp                    # open exactly that one port
+```
+
+Two caveats. A fixed data port serves **one session at a time**; a second concurrent session finds it
+busy and transparently falls back to a random port + hole-punch (logged). And `--data-port` streams
+to the client's *reported* address, so use it only where that address is reachable — a flat LAN, or a
+port-forward that doesn't remap the client's source. Leave it **off** (the default) to keep the
+NAT-crossing hole-punch. On a normal single-LAN setup you can also just leave the data port closed and
+accept the one-time ~2.5 s punch-timeout, or not run a host firewall on a trusted LAN at all.

 ## Firewall
 
-If the host box runs a firewall, open the ports it listens on. The **native `punktfunk/1`** plane:
+**Stock Arch ships no firewall** — every port is open by default, so there is nothing to do.
+Spins that enable one **do not** get their ports opened for you: an Arch package never touches the
+admin's running firewall. **CachyOS is the common case** — it ships `ufw` enabled by default (not
+firewalld), so out of the box the host is unreachable until you allow it. Some other spins (e.g.
+EndeavourOS) enable `firewalld` instead.
+
+The `punktfunk-host` package ships openers for **both** — a ufw application profile
+(`/etc/ufw/applications.d/punktfunk`) and firewalld service definitions
+(`/usr/lib/firewalld/services/`) — so enabling is one command whichever you run:
+
+```sh
+# ufw (CachyOS, and Ubuntu once you enable ufw) — reads the profile at once, no reload needed:
+sudo ufw allow punktfunk-native        # the native-only host (the default)
+sudo ufw allow punktfunk-gamestream    # …or add this for the Moonlight/GameStream host
+
+# firewalld (EndeavourOS and other Fedora-like spins):
+sudo firewall-cmd --reload                                        # pick up the installed def
+sudo firewall-cmd --permanent --add-service=punktfunk-native
+#                              --add-service=punktfunk-gamestream  # …for the Moonlight host
+sudo firewall-cmd --reload
+```
+
+`punktfunk-gamestream` opens the fixed Moonlight ports + mDNS; `punktfunk-native` opens the QUIC
+control port (UDP 9777) + mDNS. Enable both if the host runs `serve --gamestream` (which serves
+both planes). The **data plane is an *ephemeral* UDP port** the client opens with a hole-punch, so
+there is no fixed data port in either service — the host streams back out through the path the
+client opened, which any firewall that allows outbound UDP (the default) passes. The mgmt REST API
+(TCP 47990) binds to loopback by default — leave it closed unless you move it off loopback with
+`--mgmt-bind IP:PORT` (which then requires `--mgmt-token`).
+
+If you installed the **web console** (`punktfunk-web`) and want it reachable from another device,
+open its port with the matching one-liner — `sudo ufw allow punktfunk-web` or `sudo firewall-cmd
+--permanent --add-service=punktfunk-web && sudo firewall-cmd --reload` — which opens **TCP 47992**
+(HTTPS, login-gated). The mgmt API (47990) stays loopback-only.
+
+Prefer explicit rules (or a firewall the shipped profiles don't cover)? Open the ports directly.
+The **native `punktfunk/1`** plane:
 
 - **QUIC control plane: UDP 9777** (`serve --native-port N` to change).
-- **Data plane: an *ephemeral* UDP port** — negotiated per session, so there is no fixed port to
-  open. For a restrictive firewall you'd need to allow a UDP range (the repo does not pin one).
+- **Data plane: a separate UDP port.** By default it's *random* — the host binds `0.0.0.0:0` and
+  tells the client which port it got. Video flows host → client, but the **client sends the first
+  packet** (a hole-punch), so the host learns the client's real source and streams back — this
+  traverses NAT / inter-VLAN with no forwarded port. **You normally don't open it:** if a deny-inbound
+  firewall drops the punch, the host waits ~2.5 s and falls back to the client-reported address, and a
+  stateful firewall then admits the return (it just adds ~2.5 s to session start). To skip that delay,
+  pin it with **`serve --data-port <PORT>`** (or `PUNKTFUNK_DATA_PORT`): the host binds that fixed
+  port and streams direct (no punch-wait) — open exactly that one port. A fixed port serves one
+  session at a time (concurrent ones fall back to random + hole-punch), and direct mode needs the
+  client's reported address to be reachable (flat LAN / a non-remapping port-forward).

+#     sudo ufw allow punktfunk-native        # the secure native punktfunk/1 host (the default)
+#     sudo ufw allow punktfunk-gamestream    # add GameStream/Moonlight compat (opt-in)

+#     sudo ufw app info punktfunk-native     # show what a profile opens

+# Same port map as the firewalld services. The punktfunk/1 DATA plane is an

+# hole-punches, so a deny-inbound firewall still works (it just adds ~2.5 s at
