MelumiyaChat v0.9.10 — World Bible + Character Search Autofill

WORLD BIBLE
- Name + Description are now only the Overview.
- Added History & Backstory for pre-RP events.
- Added Background Facts for small persistent facts.
- Added structured Groups/Factions, Important Objects, World Rules and Story Timeline.
- Existing Characters, Relationships, Core Canon, Locations, Secrets/Knowledge, Current State and Physical Continuity remain wired.
- Existing legacy pre-RP timeline data is preserved and migrates into the new structure on edit.
- Memories remain separate from World Bible.
- User-authored canon remains authoritative.

CHARACTER SEARCH AUTOFILL
- The live melumiyachat-character-autofill backend is upgraded to v2.
- Search results are extracted into structured fields before Description is generated.
- Small verified facts can populate fields directly.
- Unsupported facts are left blank instead of invented.
- General Backstory now receives life_history.background from autofill.

REGRESSION TARGET
- Xaden Riorson should produce multiple structured researched fields when sources support them, rather than only a Description.
