### Release 187
- Fixed a regression where character-card auto-update could clear `relationshipContent` when older freeform relationship text failed the new normalizer
- Relationship auto-update now preserves existing non-empty relationship text unless there is a valid normalized replacement
- Tightened keyword review writeback so rejected candidates no longer delete existing stable aliases/keywords and then get re-added in later rounds
- Added regression tests covering legacy relationship preservation and conservative keyword retention
- Version bumped to 187 (`2.2.30`)
