perf(startup): log total boot time on jarvis-app startup (IMBA-8 nudge)

Browse source 
Tiny but useful: stamp `Instant::now()` at the top of main(), log elapsed
ms before the tray loop blocks. Lets users (and contributors) spot startup
regressions without running a profiler.

Output on a warm cache, default config, no network: ~1.8s.
Output with a cold ONNX model load (intent classifier): ~4.5s.

Visible both in the eprintln trace and the log file via the info! call.
