jedarden e97a8413b5 feat(bf-2f5): watchdog timeout implementation complete 
Implement comprehensive watchdog timeout mechanism to prevent indefinite hangs
when child process wedges. All four timeout types are now enforced:

Timeout Types:
- PTY first-output timeout (default 90s): Detects if child produces no PTY output
- Stream-json first-output timeout (default 90s): Detects if child emits no stream-json events
- Overall timeout (default 3600s): Maximum session duration
- Stop hook timeout (default 120s): Detects if Stop hook doesn't fire after prompt injection

Timeout Behavior:
- Sends SIGTERM to child process
- Signals event loop via self-pipe to wake up
- Calls kill_child() which waits 2s then SIGKILL if needed
- Writes clear diagnostic to stderr
- Tears down temp resources via CleanupGuard
- Exits with code 124 (GNU timeout convention)

CLI Arguments:
- --timeout <seconds>: Overall timeout
- --first-output-timeout <seconds>: PTY first-output timeout
- --stream-json-timeout <seconds>: Stream-json first-output timeout
- --stop-hook-timeout <seconds>: Stop hook watchdog timeout

Testing:
- All 90 unit tests pass (6 watchdog-specific tests)
- Integration tests verify end-to-end timeout behavior

This ensures marathon loop/NEEDLE can retry cleanly instead of hanging indefinitely.
