Release v1.9.0

Added

• Support for devcode 6515 (ANENJI ANJ-HHS-11KW-48V-WIFI) with sensor mappings, operating mode normalization, and PV temperature support (#13, thanks to @dekov3 for the CLI analysis data).
• Support for devcode 6544 (ANENJI ANJ-HHS-11KW-48V) with sensor mappings, operating mode normalization, and split-phase output support (#11, thanks to @blihtar for the CLI analysis data).

Fixed

• Fetch "Battery percentage" (SOC) from the parameters API endpoint for devcode 2376, since this sensor only exists in queryDeviceParsEs and not in queryDeviceLastData. The coordinator now fetches parameters in parallel when a devcode declares parameter_sensor_names, merges them with dedup into the device data, and the existing title mapping produces the State of Charge entity (#12, thanks to @baziliolg for reporting and providing analysis data).
• Graceful per-device error handling: a single device returning ERR_NO_RECORD (API error 12) no longer blocks all other devices from loading. Failed devices are skipped with a warning log, and UpdateFailed is only raised when every collector fails.
