Pilot v2: Core implementation + battery telemetry
Major updates: - Complete Rust rewrite (pilot-v2/) with working MQTT client - Fixed MQTT event loop deadlock (background task pattern) - Battery telemetry for Linux (auto-detected via /sys/class/power_supply) - Home Assistant auto-discovery for all sensors and switches - Comprehensive documentation (AVANCEMENT.md, CLAUDE.md, roadmap) - Docker test environment with Mosquitto broker - Helper scripts for development and testing Features working: ✅ MQTT connectivity with LWT ✅ YAML configuration with validation ✅ Telemetry: CPU, memory, IP, battery (Linux) ✅ Commands: shutdown, reboot, sleep, screen (dry-run tested) ✅ HA discovery and integration ✅ Allowlist and cooldown protection Ready for testing on real hardware. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
