shawn 44cf978873 Wire 4CM routing: JackAudioClient + boot orchestration + set_routing_mode() 
- Add JackAudioClient class to src/system/audio.py — real-time JACK
  client owning ports and a process callback that streams audio through
  the DSP pipeline. Handles mono (1ch I/O) and stereo 4CM (2ch I/O).
- Wire PedalApp.boot(): read audio.mode from config, set pipeline
  routing_mode (mono/4cm), create and start JackAudioClient with
  matching channel count.
- Add PedalApp.set_routing_mode(mode) — hot-switch between mono and
  stereo_4cm at runtime: updates pipeline.routing_mode, restarts JACK
  client with new channel count via set_channel_count(), re-connects
  JACK ports.
- Wire shutdown: stop JackAudioClient before MIDI/footswitch.
- Export JackAudioClient from src.system.__init__.
- 53 tests pass (22 integration + 31 audio).

shawn c2071a9724 feat(audio): Focusrite 2i2 stereo JACK config for 4CM 
Adds:
- AudioConfig.mode field: 'mono' (default) or 'stereo_4cm'
- capture_channels / playback_channels properties for dynamic JACK -i/-o counts
- FOCUSRITE_PROFILES dict with focusrite_2i2_3gen entry
- AudioSystem.channel_mapping_help() static method
- stereo_4cm port auto-connect wiring (4 cable method)
- Systemd service content uses dynamic channel counts
- Default config YAML includes 'mode: mono'
- 11 new tests (31 total pass)
- Focusrite 4CM wiring docs in docs/config-audio.md

shawn c38a7b0fd8 Add main entry point + systemd services + integration tests 
New files:
  main.py                   - PedalApp: boots all subsystems in order,
                              wires MIDI/footswitch callbacks, graceful
                              teardown reverses boot order
  src/system/config.py      - YAML config loader with deep-merge
                              (separated to avoid hardware deps)
  src/system/services.py    - systemd unit generator for pedal.service
                              + multi-fx-pedal.target
  scripts/install_service.sh - copies project, creates venv, installs
                              + enables service units
  tests/test_integration.py - 41 tests: boot, routing, display sync,
                              teardown, systemd content, CLI, edge cases

Modified:
  tests/conftest.py         - add project root to sys.path
