fix: increase timeouts for slow systems

Phase 2 of worker lifecycle fix - applying timeout increases:

- hook-constants.ts: DEFAULT 120s→300s, HEALTH_CHECK 1s→30s, RETRIES 15→300
- worker-service.ts: context init 30s→300s, MCP 15s→300s, PowerShell 5s→60s
- BranchManager.ts: GIT_COMMAND 30s→300s, NPM_INSTALL 120s→600s
- hooks.json: worker start/restart 30s→180s, hook execution 120s→300s
