feat: add KWin/KDE Plasma screen capture via xdg-desktop-portal ScreenCast + PipeWire

Add a second capture backend for compositors without wlr-screencopy
(KWin, GNOME, etc.) using the xdg-desktop-portal ScreenCast interface
and PipeWire DMA-BUF streaming.

New files:
- src/backend_detect.rs: auto-detect wlr-screencopy vs portal backend
- src/cap_portal.rs: Portal session setup + PipeWire DMA-BUF thread
- src/state_portal.rs: StatePortal encoder pipeline (DMA-BUF → VAAPI)

Changes:
- Cargo.toml: add ashpd 0.13, tokio 1, pipewire 0.9, libspa 0.9,
  crossbeam-channel 0.5
- src/args.rs: add --backend CLI flag
- src/avhw.rs: extract create_encoder() from inline State code
- src/main.rs: route to portal or wlr-screencopy based on backend
- src/state.rs: fix params.destroy() on dup failure, cleanup
  in_flight_surface on copy fail, use create_encoder()
- tests/integration_test.rs: add --backend flag tests

feat: Phase 1 MVP with audit fixes — Wayland screen capture + VAAPI encoding

Phase 1 MVP implementation of wl-webrtc: Wayland screen capture tool
with hardware-accelerated VAAPI H.264 encoding and WebTransport output.

Includes all 9 runtime bug fixes from code audit (fix-audit-issues plan):

CRITICAL:
- C2: h264_metadata BSF with repeat_sps/repeat_pps in encode pipeline
- C4: FpsLimit wired as timing gate in on_copy_complete

HIGH:
- C3+A2: DRM device discovery via dmabuf feedback MainDevice event,
  unified resolve_drm_path() helper (CLI > compositor > auto > fallback)
- H2: Separate physical_size (mm) from mode_size (pixels) in wl_output
- H1+A3: Multi-output warning + named-output-not-found error

MEDIUM:
- M5: tv_sec u32->u64 to avoid Y2106 timestamp truncation
- M4: Guard against SHM Buffer event (DMA-BUF only)

Key components:
- src/avhw.rs: FFmpeg VAAPI encoder + filter graph + BSF pipeline
- src/state.rs: Wayland event loop + output negotiation + screencopy
- src/cap_wlr_screencopy.rs: wlr-screencopy capture source
- src/fps_limit.rs: Frame rate limiting with configurable target
- src/transform.rs: Frame format conversion utilities
