fix(radarr): improve event type parsing and grab event validation

- Fix string-based event type parsing (grabbed, downloadFolderImported, etc.)
- Filter grab events to only count actual downloads with metadata
- Fix JSON parsing errors for dict-type event data
- Enhanced chronological processing for accurate import date detection
- Validate grab events require sourceTitle or indexer info

Fixes issue where library addition events were mistaken for download grabs,
ensuring only real download timestamps are used for

+### Fixed
+- **Radarr Client**: Fixed event type parsing for string-based event types (grabbed, downloadFolderImported, etc.)
+- **Radarr Client**: Improved grab event detection to filter out library addition events and only count actual download grabs
+- **Radarr Client**: Fixed JSON parsing errors when handling event data that's already a dictionary
+- **Radarr Client**: Enhanced validation of grab events to require download metadata (sourceTitle or indexer)
+
+### Improved
+- **Radarr Client**: Better chronological event processing to find earliest actual download dates
+- **Radarr Client**: More accurate import date detection by validating grab events have real download information
+
+## [0.4.0] - 2025-01-08
 ### Changed
 - Switched to using Radarr's numeric event types for more reliable import detection
   - Added constants for EVENT_TYPE_GRABBED (1), IMPORTED (3), etc.
