V1.6-beta6

Multi-Account Support

Added

• True multi-account runtime support: Multiple Google accounts can now run simultaneously with proper isolation
  • Each account appears as a separate integration entry: "Google Find My Device (email@example.com)"
  • Device identifiers now include entry_id to prevent conflicts between accounts sharing the same device
  • Integration diagnostic sensors (stats, polling) are now per-account with unique identifiers
  • Integration diagnostic devices now show account email: "Google Find My Integration (email@example.com)"

Changed

• Config flow entry titles now include the account email for easy identification
• Device identifiers updated across all platforms to include entry_id:
  • Device trackers (device_tracker.py)
  • Sensors (sensor.py)
  • Binary sensors (binary_sensor.py)
  • Buttons (button.py)
• Per-user encryption key storage: owner_key and shared_key now stored under per-user cache keys (e.g., owner_key_email@example.com)
• Cache management: Removed global cache provider registration to prevent cross-account cache conflicts

UX Improvements

Added

• Clear messaging in options flow to prevent confusion when configuring vs. adding accounts:
  • Options menu shows: "Configuring account: email@example.com" with instructions to use "+ Add Integration" for additional accounts
  • Update Credentials screen warns: "This will update credentials for the current account only"
