perf: ArcSwap lock-free screen sharing, reader park, scratch buffer, deadlock fix (#78)

* perf: ArcSwap lock-free screen sharing, reader park, scratch buffer,
deadlock fix

- Replace `Arc<Mutex<Screen>>` with `Arc<ArcSwap<Screen>>` — lock-free
  atomic
  pointer swap eliminates Mutex contention and Screen clone on UI
  thread.
- Reader parks after each publish batch (`while dirty { park() }`),
  wakes on
  unpark from `screen()` after consuming dirty. Drop impl sets
  shutdown+unpark
  to prevent zombie threads.
- Fix 3600s freeze: arm coalesce deadline after drain_pending when dirty
  windows exist, preventing recv_timeout blocking forever when PtyWakeup
  arrives between handler(None) and drain_pending.
- Reuse scratch `Vec<Cell>` in WindowDrawState across frames instead of
  allocating+deallocating a fresh Buffer per window per frame (~200MB at
  4K).
- Remove Debug supertrait from Overlay and BottomPanel traits; replace
  derived Debug on WmMenuOverlay with manual impl that skips generic `R`
  field.
- Increase PTY read buffer from 4KB to 64KB for better batching.
- Bump version to 0.8.4-alpha.

* Add more tests
