- Test server lifecycle (start, stop, isRunning)
- Test HTTP endpoints (GET /health, GET /status, 404, 405)
- Test PID file management (create, remove, stale cleanup)
- Verify server throws on double-start or existing PID file
- Define EventBus interface (PORT) with emit, on, off, once methods
- Define base DomainEvent interface with type, timestamp, payload
- Implement EventEmitterBus class (ADAPTER) using Node.js EventEmitter
- Export createEventBus() factory function for easy instantiation
- CoordinationServer class using node:http
- GET /health returns status, uptime, processCount
- GET /status returns full server state and process list
- PID file at ~/.cw/server.pid prevents duplicate servers
- CLI --server flag and --port option for server mode
- CW_PORT env var support for custom port
- ProcessManager class with execa for child process spawning
- spawn() starts detached background processes
- stop() graceful shutdown with SIGTERM then SIGKILL after 5s timeout
- stopAll() terminates all managed processes
- restart() stops and respawns with same config
- isRunning() probes actual process state
- Proper promise handling for killed processes
- ProcessLogWriter class for stdout/stderr capture
- Timestamps each line with [YYYY-MM-DD HH:mm:ss.SSS] format
- Backpressure handling via drain events
- getStdoutStream/getStderrStream for direct piping
- Module index exports types, classes, and createLogger helper
- createLogger convenience function for default config
- LogLevel, LogEntry, LogConfig types in types.ts
- LogManager class with directory management
- Cross-platform paths using node:os and node:path
- ensureLogDir/ensureProcessDir for directory creation
- getLogPath returns ~/.cw/logs/{processId}/{stream}.log
- cleanOldLogs removes directories older than N days
- listLogs enumerates all process log directories
- Add createCli() function with commander configuration
- Register placeholder commands: status, agent, task
- Add graceful error handling for uncaught exceptions
- Read version from package.json via index.ts export
