add Starlight docs site, LoRa examples, and clean up .gitignore
- Starlight docs: 28 pages covering getting started, guides, tool
reference, concepts (architecture, dynamic tools, runtime comms)
- LoRa examples: channel scanner, quality analyzer, multi-SF receiver
with both .grc and .py forms, plus ADSB+LoRa combo test
- .gitignore: exclude generated artifacts (*_patched_*.py, *.wav,
docs build cache, tests/scratch/)
- Add .mcp.json for local MCP server config
- Sync uv.lock with date-based version
