v1.2.0

Changed

• Full integration overhaul to 2026 Home Assistant standards:
  • Boot time capture rewritten as a removable logging.Filter
    (BootTimeMonitor) — the previous logger.info monkey-patch is gone;
    the hook detaches itself as soon as the boot time is captured (zero
    residual cost) and is also cleanly detached on config entry unload.
  • Typed ConfigEntry.runtime_data replaces hass.data[DOMAIN] (no more
    leak on unload).
  • Setup timings now come from the public
    homeassistant.setup.async_get_setup_timings() helper instead of the
    private hass.data["setup_time"] (multi-version format handling removed).
  • Sensor modernised: RestoreSensor, native_value, duration device class,
    s unit, measurement state class, display precision, has_entity_name
    and a service device (manufacturer/model/version/configuration URL).
    unique_id is unchanged — existing history and automations are preserved.
  • The boot value is now restored across restarts: the sensor no longer stays
    unknown when the integration is added on an already-running instance.
  • Per-integration setup-timing attributes are excluded from recorder history
    to avoid database bloat (still available live and in diagnostics).
  • integration_type corrected from helper to service (the integration
    now appears on the Integrations dashboard) and single_config_entry: true
    added.
  • Minimum Home Assistant version raised to 2025.1.0.
• Repository modernised: CI, HACS/hassfest validation, Renovate, release-please
  release pipeline, pre-commit (prek), devcontainer and full documentation.

Added

• Diagnostics support (boot time + per-integration setup timings dump).
• Behavioral test suite: 26 tests, 100% coverage
  (pytest-homeassistant-custom-component).

Removed

• Legacy YAML configuration support (start_time: + import flow). Existing
  config entries are unaffected; the integration is configured via the UI.
