feat(daemon): Session 5 — daemon lifecycle (Daemon Spec Phase B)

Add lib/daemon.mjs with full process lifecycle: startDaemon (foreground loop, SIGTERM/SIGINT graceful shutdown, cancellable sleep, stale PID crash recovery, run_on_start), stopDaemon (SIGTERM → SIGKILL with configurable timeout), getDaemonStatus (PID check, log-derived last-pass and next-pass). Pure helper exports (getPidPath, getLogPath, writePidFile, readPidFile, removePidFile, isProcessAlive, detectStalePid, appendDaemonLog, readDaemonLog, isIdle, validateLlmConnectivity) are fully injectable for testing — no real LLM calls in the test suite.

CLI: daemon start [--background] | stop | status | log [--tail <n>]. MCP: daemon_status tool returns running state, PID, last/next pass times.

74 new tests (729 total, 0 failures, 0 regressions).
