Jannis 78c8a23131 Fix setup failure when BMS not immediately reachable 
Don't connect eagerly in async_setup — let the first coordinator poll
handle it. If the BMS is out of range at startup, UpdateFailed becomes
ConfigEntryNotReady and HA retries automatically instead of crashing.

Jannis db45679c12 Support ESPHome BLE proxies via HA Bluetooth subsystem 
Use async_ble_device_from_address() to resolve the BMS through whichever
adapter (local or ESPHome proxy) can reach it, instead of connecting by
raw MAC address directly. BleakClient now receives a BLEDevice object.

Jannis 4a769bf50f Initial commit: Xiaoxiang Smart BMS Home Assistant integration 
- BLE GATT communication via bleak (UART-over-GATT, service 0xff00)
- Parses 0x03 (general info) and 0x04 (cell voltages) frames
- Protocol verified against official RS485/UART spec V4
- DataUpdateCoordinator with 5s poll interval (configurable 2-60s)
- Auto-reconnect on BLE disconnect
- Config flow: BT auto-discovery + manual MAC entry + options flow
- Sensors: voltage, current, power, SoC, capacity, cycles, temps, cells, cell delta
- HACS-ready (hacs.json, manifest.json)
