Extended the parser to recognize DSM update available notifications in addition
to update cancelled and package out-of-date notifications. All variants fall
under same Updates job type for unified monitoring.
Changes:
- Added "new DSM update", "Auto Update has detected", "new version of DSM", "Update & Restore" to detection patterns
- Extended hostname extraction regex to match "detected on HOSTNAME"
- Now recognizes three notification types: update cancelled, packages out-of-date, update available
- All existing patterns remain functional (backward compatible)
- Updated changelog
