feat(client-linux): native GTK4 client — stage 1, first light at 1080p60
New crate crates/punktfunk-client-linux (binary punktfunk-client), the
native Linux client on the Option A architecture (2026-06-12 research):

- GTK4/libadwaita shell linking punktfunk-core directly (no C ABI):
  mDNS host list, TOFU fingerprint prompt, SPAKE2 PIN pairing dialog,
  preferences (mode/bitrate/gamepad/shortcut capture), stats overlay,
  --connect host[:port] for scripting.
- Video: FFmpeg software HEVC decode (LOW_DELAY, slice threads) ->
  RGBA -> GdkMemoryTexture inside GtkGraphicsOffload (the dmabuf
  subsurface path lights up when VAAPI lands; black-background keeps
  fullscreen scanout-eligible).
- Audio: Opus -> PipeWire playback stream, the host virtual-mic's
  adaptive jitter ring inverted.
- Input: keyboard as the exact inverse of the host VK table (evdev
  keycodes, layout-independent; unit-tested), absolute mouse through
  the Contain-fit transform, WHEEL_DELTA(120) scroll, compositor
  shortcut inhibition while streaming, Ctrl+Alt+Shift+Q release chord,
  F11 fullscreen. SDL3 gamepad capture (single pad-0 model) + rumble
  and DualSense lightbar feedback on the same thread.
- Session pump owns video+audio pulls; the gamepad thread owns
  rumble+hidout — possible because NativeClient's plane receivers are
  now mutexed, making it Sync (Arc-shared, compiler-verified per-plane
  contract instead of the ABI's manual assertion).
- Linux-gated deps + a stub main keep cargo build --workspace green on
  macOS.

Validated live against serve --native on this box: 1920x1080@60,
locked 60 fps, capture->decoded p50 ~6.4 ms (software decode, debug
build). Teardown keys off AdwNavigationPage::hidden — NavigationView
push fires a transient unmap/map cycle that must not end the session.

# NOTE: deliberately NOT `panic = "abort"`. punktfunk-core ships as a cdylib/staticlib into
# third-party apps (Swift/Kotlin/C) and its C ABI catches panics at the boundary
# (`catch_unwind` → `PunktfunkStatus::Panic`). `panic = "abort"` would make that guard a
# no-op and let a stray panic abort the embedding application. Unwinding keeps the
# documented isolation guarantee real.
# The per-frame hot path must stay fast even in dev builds.
