Add a lightweight, self-contained phase tracer for measuring end-to-end bbctrl restart and Pi boot time. Disabled by setting BBCTRL_TRACE=0. - src/py/bbctrl/Trace.py: monotonic-anchored event log + sd_notify helper. - bbctrl/__init__.py: marks for imports, args parsed, ioloop, web init, listen, and an sd_notify READY=1 once HTTP is bound. - bbctrl/Ctrl.py: spans around each subsystem (avr, i2c, lcd, mach, preplanner, jog, pwr, hooks, aux, mach.connect). - bbctrl/Comm.py: avr.firmware_rebooted mark. - bbctrl/Web.py: TimingHandler (GET /api/diag/timing) and UITimingHandler (PUT /api/diag/timing/ui), plus a ws.first_open mark. - src/js/restart-timing.js + app.js: UI-side performance.now() marks (script.load, ws.open, ws.first_msg, ui.first_state, window.load), posted once to the controller. - scripts/bbctrl.service: stdout/stderr -> journal so TRACE lines are visible via journalctl -u bbctrl. (Was StandardOutput=null.) Revert: git revert this commit. To disable at runtime without reverting, set BBCTRL_TRACE=0 in the bbctrl service environment.
