enricobuehler 927a571414 feat(console): touch-mode setting + request-access pairing + polish
Extend the gamepad/console shell (pf-console-ui) to parity with the other clients:

- Settings gain a Touchscreen → Touch mode row (Trackpad / Direct pointer /
  Touch passthrough), the one couch-relevant Settings field the screen lacked.
- The pair screen adds the no-PIN delegated-approval path: a "Request access"
  action (only when the host advertises a fingerprint to pin) opens a connect the
  host PARKS until the operator approves this device, then persists it as paired.
  A role-based row model keeps the cursor off stale indices; manual hosts stay
  PIN-only, matching the desktop shells.
- Threads request_access through OverlayAction::Launch and ConnectIntent; the
  shell shows a "Waiting for approval…" takeover, and the session binary parks on
  a 185 s budget (PendingApproval → persist-as-paired via on_connected).

Auto-wake (WoL) was already implemented end-to-end and is left as-is.

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 while the overlay tier isn't Off (always the full detailed text, whatever the OSD shows; --stats forces the overlay 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 cycles the OSD tier live — Off → Compact (one line: fps · latency · Mb/s) → Normal (mode + end-to-end percentiles) → Detailed (decoder path + per-stage latency equation); any tier but Off also emits 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 (auto: Vulkan Video → VAAPI → software on Linux, Vulkan Video → D3D11VA → software on Windows): FFmpeg's Vulkan Video decoder runs on the presenter's own device where the stack supports it (every vendor, zero copy); VAAPI dmabufs import per-plane elsewhere (D3D11VA textures on Windows); software is the universal fallback. 10-bit Main10 and HDR10 are advertised (VIDEO_CAP_10BIT|HDR): P010 decodes through all three paths, and PQ streams present on an HDR10/ST.2084 swapchain when the desktop offers one (KDE HDR, gamescope) or tone-map in-shader to SDR when it doesn't (PUNKTFUNK_TONEMAP_PEAK tunes the rolloff, default ≈1000 nits). The host still gates the upgrade behind its PUNKTFUNK_10BIT policy.

Debug/bisect knobs: PUNKTFUNK_DECODER=vulkan|vaapi|d3d11va|software, PUNKTFUNK_PRESENT_MODE= mailbox|immediate (default FIFO), PUNKTFUNK_VK_DEVICE=<index> (multi-GPU), and PUNKTFUNK_HW_FAULT=import (fault every VAAPI dmabuf import — proves the three-strike demotion to software on healthy hardware).
