v3.4.1: Fix Present Characters not included in <previous> section for separate generation mode

- Fixed bug where Present Characters data wasn't appearing in the <previous> section when generating new trackers in separate mode
- Root cause: committedTrackerData.characterThoughts is stored as a JS array, not a JSON string
- Solution: Check data type before parsing - handle both object/array and string formats
- Present Characters data now correctly included in unified previous tracker JSON regardless of showCharacterThoughts setting
