- Add removeCharacter() function to delete characters from panel and saved data
- Remove character from both lastGeneratedData and committedTrackerData
- Add X button to character card header with hover effects
- Button removes character from display and prevents re-inclusion in next generation
- Updates are persisted to chat metadata
