Development Release 0.7.0-dev

⚠️ Warning: This is a development pre-release for testing — it may contain unstable features and is not recommended for production use.

Connection diagnostics on the "Enhanced" device

New diagnostic entities: connection_active (connectivity), connection_state, connection_last_read / connection_last_write (timestamps), and connection_read_errors / connection_write_errors (counters with a per-category breakdown: timeout / connection / invalid address / other, plus newest failure)
Translations in English, German and Dutch

Raw register snapshot in the diagnostics download

The diagnostics download now includes a fresh raw snapshot of all four register spaces (input, holding, coil, discrete), keyed by raw unit address, plus per-space failure info
Holding registers fall back to chunked blocks so partial data is preserved and reported instead of failing the whole download

The integration no longer manages Modbus connections itself — Home Assistant's shared modbus component now owns the connection lifecycle:

Connection testing in config, reauth, reconfigure and repair flows uses a temporary-unit probe; setup and unload never close shared clients
A lost device connection raises ConfigEntryNotReady (automatic retry) and opens a repair issue instead of breaking the entry
New configurable Modbus unit ID (1–247, default 1) in the config and reconfigure flows — existing entries migrate automatically (v1→v2, no action required)
Legacy pymodbus-direct client removed; pymodbus now arrives at runtime via the modbus-connection[pymodbus] extra
Reads/writes ported to flat-list unit calls; the polling batch layout is consolidated in shared constants so polling and snapshot paths cannot drift apart

Home Assistant 2026.9 or higher (previously 2024.1) — required for HA's shared modbus component that this release is built on

Full test suite green (510+ tests, incl. new diagnostics and snapshot coverage), ruff check and ruff format clean
