dailz 74f4dc826d perf(portal): achieve 58-60fps PipeWire screen capture
- Force PipeWire quantum=512 via NODE_FORCE_QUANTUM (48000/512=93Hz scheduling)
- Switch to libx264 ultrafast/zerolatency with 6 threads
- Use two-phase poll_and_encode: blocking recv_timeout for first frame,
  non-blocking try_recv drain for subsequent frames
- Remove fps_limit from portal path (PW already rate-limits via quantum/KWin;
  fps_limit's min_interval was silently dropping ~10% of valid frames)
- Remove diagnostic instrumentation (TIMING/PIPEWIRE logs, timing fields,
  pw_stats counters)
- Add lightweight production stats: per-10s fps log + shutdown summary
- Prefer libx264 over libopenh264 (better quality at same speed)
