Doctor checks spawned subprocesses (gh, opencode, sg) without timeouts,
causing the process to hang indefinitely if any binary was stuck.
The OS would then SIGKILL the process (exit code 137).
- Add spawnWithTimeout utility with 10s per-spawn timeout and proper
cleanup (timer cleared on success, proc.exited awaited after kill)
- Capture both stdout and stderr to preserve gh auth status behavior
- Add 30s overall doctor command timeout with JSON-mode support
- Distinguish timeout errors from other failures in runner
- Update all doctor check subprocess calls to use timeouts
