"""Diagnostic/overview methods mixin for SonarrClient.

Extracted from sonarr_client.py. Groups two methods that don't touch
the core HTTP plumbing and are called from diagnostics/UI surfaces
rather than the search pipeline:

- ``extended_health_check`` — five-step diagnostic snapshot
  (connection, API version, library access, webhook status, health
  issues) used by the settings UI's per-instance health panel.
- ``get_library_info`` — flat series/episode count overview used by
  the dashboard and the integration export.

Both rely on ``self._get`` + ``self.url`` from the SonarrClient host
class; mixed in via multiple inheritance so the class location stays
at ``sonarr_client.SonarrClient`` for all test patches.
