enricobuehler cbcd7a5c40 refactor(client): relm4 desktop shell; delete legacy presenter + coverflow (phase 5)
The GTK client becomes a relm4 component tree: AppModel owns the window,
trust gate (rules 1-3), and the spawned session child's lifecycle as
typed messages; the hosts page is a child component with a
FactoryVecDeque of host cards — the HostsCallbacks Rc<dyn Fn> bag, the
busy Cell, and the Rc<RefCell<HostsUi>> cross-page pokes are gone.
Trust/settings/library dialogs stay plain GTK, invoked from update with
a ComponentSender.

Deleted with the in-process presenter: ui_stream.rs, video_gl.rs,
ui_gamepad_library.rs, launch.rs, the khronos-egl dep, and the
PUNKTFUNK_LEGACY_PRESENTER hatch. Every stream (and the console library)
now runs in punktfunk-session; the shell spawns it for card connects and
exec's it for --connect/--browse so the Decky wrapper keeps working. The
request-access flow gains --connect-timeout + a CancelHandle that kills
the child. Screenshot scenes re-pointed onto the components (verified:
hosts + library self-capture; the dialog scenes present correctly and
capture under a GL renderer); the gamepad-library scene is gone with the
page.

punktfunk-session

The Vulkan session binary: one stream per invocation in an SDL3 window — no UI toolkit, no widgets, terminal stats. The power-user / gamescope stream client, and the stage-2 presenter of the Linux client re-architecture (punktfunk-planning: linux-client-rearchitecture.md).

punktfunk-session --connect host[:port] [--fp HEX] [--launch id] [--fullscreen] [--stats]
punktfunk-session --browse host[:port] [--mgmt PORT] [--fullscreen]

--browse opens the console game library (the Skia coverflow over the animated aurora) instead of connecting: A launches the focused title as a stream in the same window, session end returns to the library, B quits (Gaming Mode returns). Paired hosts only — pairing is the desktop client / Decky plugin's job. PUNKTFUNK_FAKE_LIBRARY=<file.json> feeds canned entries with no host (portrait paths starting with / load from disk).

Reads the same identity / known-hosts / settings stores as the desktop client (punktfunk-client) — pair there (or via its headless --pair) first; this binary never connects to a host it has no pinned fingerprint for (--fp HEX overrides the store).

Stdout is the machine interface: {"ready":true} after the first presented frame, stats: … once per second (Ctrl+Alt+Shift+S toggles, --stats forces on), one {"error"|"ended": …} JSON line on the way out. Logs go to stderr. Exit codes: 0 clean end, 2 connect failed, 3 trust rejected / pairing required, 4 presenter init failed.

In-stream keys match the desktop client: click captures input (Ctrl+Alt+Shift+Q releases), Ctrl+Alt+Shift+D disconnects, F11 toggles fullscreen; the controller escape chord (L1+R1+Start+Select, hold to disconnect) works the same.

The default build carries the Skia console UI (ui feature): the stats OSD and capture hint render in-window (Ctrl+Alt+Shift+S toggles both the OSD and the stdout mirror). --no-default-features is the ~5 MB power-user build — same streaming, stats on stdout only, no Skia anywhere in the dependency tree.

Decode follows the Settings preference: VAAPI frames import zero-copy into Vulkan (per-plane dmabuf + the stream's CICP-driven CSC shader); boxes whose driver can't import (NVIDIA proprietary by design) fall back to software decode automatically. Debug/bisect knobs: PUNKTFUNK_DECODER=software|vaapi, PUNKTFUNK_PRESENT_MODE= mailbox|immediate (default FIFO), PUNKTFUNK_VK_DEVICE=<index> (multi-GPU), and PUNKTFUNK_HW_FAULT=import (fault every dmabuf import — proves the three-strike demotion to software on healthy hardware). HDR/P010 and the Skia console UI (--browse) are later phases of the plan.
