Max Johnson 6b1091fc92 app-server: harden disconnect cleanup paths (#12218 )

Hardens codex-rs/app-server connection lifecycle and outbound routing
for websocket clients. Fixes some FUD I was having

- Added per-connection disconnect signaling (CancellationToken) for
websocket transports.
- Split websocket handling into independent inbound/outbound tasks
coordinated by cancellation.
- Changed outbound routing so websocket connections use non-blocking
try_send; slow/full websocket writers are disconnected instead of
stalling broadcast delivery.
- Kept stdio behavior blocking-on-send (no forced disconnect) so local
stdio clients are not dropped when queues are temporarily full.
- Simplified outbound router flow by removing deferred
pending_closed_connections handling.
- Added guards to drop incoming response/notification/error messages
from unknown connections.
- Fixed listener teardown race in thread listener tasks using a
listener_generation check so stale tasks do not clear newer listeners.

Fixes

  ## Tests

  Added/updated transport tests covering:

  - broadcast does not block on a slow/full websocket connection
  - stdio connection waits instead of disconnecting on full queue

I (maxj) have tested manually and will retest before landing
