add prometheus exporter + test suite
- prometheus-exporter.py: stdlib-only HTTP metrics on :9090/metrics - Exposes: ALSA status, hw_ptr rate, service health, mixer controls - MIDI counters: notes_on, notes_off, errors - test-unit.py: 10-test suite covering full MIDI→Pd→Audio pipeline - test-tone.pd, test-midi-log.pd: minimal debug patches - systemd service for exporter - install.sh/deploy updated to include exporter
