Add environmental telemetry collection (temperature, humidity, barometric
pressure, voltage) from both the repeater node (over LoRa) and companion
node (local serial). Telemetry is stored in the same EAV metrics table
with `telemetry.` prefix.
Key changes:
- Add TELEMETRY_ENABLED feature flag (defaults to OFF)
- Add telemetry-specific timeout/retry settings
- Create shared telemetry.py module with extract_lpp_from_payload()
and extract_telemetry_metrics() helpers
- Handle MeshCore API dict payload format: {'pubkey_pre': '...', 'lpp': [...]}
- Repeater: store status metrics BEFORE attempting telemetry (LoRa reliability)
- Companion: merge telemetry into single DB write (serial is reliable)
- Telemetry failures do NOT affect circuit breaker state

Implements fcntl.flock() based locking for serial transport to prevent
USB serial conflicts when collect_companion and collect_repeater run
simultaneously. This addresses Ofelia's limitation where no-overlap
only prevents a job from overlapping with itself, not other jobs.
Key changes:
- Add connect_with_lock() async context manager to meshcore_client.py
- Use non-blocking LOCK_NB with async polling to avoid freezing event loop
- Only lock for serial transport (TCP/BLE don't need it)
- 60s timeout with clear error message if lock cannot be acquired
- Update collector scripts to use new context manager
- Remove external flock from cron examples (now handled in Python)

A Python-based monitoring system for MeshCore LoRa mesh networks.
Collects metrics from companion and repeater nodes, stores them in
a SQLite database, and generates a static website with interactive
SVG charts and statistics.
Features:
- Data collection from local companion and remote repeater nodes
- SQLite database with EAV schema for flexible metric storage
- Interactive SVG chart generation with matplotlib
- Static HTML site with day/week/month/year views
- Monthly and yearly statistics reports (HTML, TXT, JSON)
- Light and dark theme support
- Circuit breaker for unreliable LoRa connections
- Battery percentage calculation from 18650 discharge curves
- Automated releases via release-please
