Replace run-spawner imports and APIs with pty-run:
- Import pty-run instead of run-spawner
- Delete setRunExitHandler registration, replace with read-time self-heal in payload()
- Remove mode validation (mode no longer exists in pty-run)
- Update spawnRun call to use new parameter names (initialPrompt, not prompt/mode)
- Replace "message" action with explicit 400 EUNSUPPORTED response
- Fix stopLaneRun to poll on status !== "gone" instead of !actualExitedAt
Adapt tests to tmux-based run model:
- Delete tests about mode-specific behavior (removed feature)
- Rewrite lane release tests using tmux.__setExecImpl mocks instead of withFakeClaude
- Update assertions to check status === "gone" instead of specific exit codes
- Update ERUNTIMEOUT test to mock tmux sessions instead of child processes
All lane-related tests pass; only pre-existing port conflicts in lane-detect.test.js remain.
