This commit fixes several issues with the MQTT discovery payload to ensure
full compliance with Home Assistant's MQTT discovery specification and match
the working configuration from the v1 implementation.
Changes:
- Add payload_available ("online") and payload_not_available ("offline") fields
to EntityConfig struct for proper availability handling in HA
- Make device_info parameters (manufacturer, model, sw_version, suggested_area)
configurable via config.yaml instead of hardcoded values
- Remove incorrect device_class "power" from cpu_usage sensor (power is for Watts, not %)
- Update config.example.yaml with documented device_info fields
The discovery payload now correctly includes all required fields for HA to
properly register and display the device with its sensors and switches.
Tested on physical PC (asus) with MQTT broker at 10.0.0.3:1883.

This commit adds support for automatic hostname substitution in configuration files.
Users can now use $hostname in device.name, device.identifiers, and mqtt.client_id
to automatically use the system's hostname.
Changes:
- Add hostname crate dependency (v0.4)
- Implement expand_variables() to replace $hostname with actual hostname
- Add get_hostname() helper function
- Update config.example.yaml to demonstrate $hostname usage
- Add test for hostname substitution
- Update config.yaml to use $hostname by default
- Add test_command.sh script for testing MQTT commands
This makes deployment easier across multiple machines without manual config changes.

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)
