Three compounding bugs caused hook failures:
1. Missing break statements in worker-service.ts switch — if async
code threw before process.exit(), execution fell through to
subsequent cases. Added break to all 7 cases missing them.
2. Unhandled promise rejection on main() — added .catch() that logs
the error and exits 0 (per project exit code strategy: don't block
Claude Code or leave Windows Terminal tabs open).
3. Redundant start commands in hooks.json — PostToolUse,
UserPromptSubmit, and Stop groups each had a standalone start
command that was redundant (the hook case already calls
ensureWorkerStarted internally). The redundant start also caused
5s latency via bun-runner.js collectStdin() timeout since Claude
Code never closes stdin.
