MelumiyaChat v0.9.9 — Character Dossier + Web Autofill

- Full structured character dossier: identity, appearance, personality, preferences,
  relationships, life history/defining events, current life, RP behaviour,
  knowledge/skills, continuity rules, and lore/powers.
- Quick Create remains available: only a name is required.
- New “Search the web & autofill” button uses authenticated public-source research.
- Imported facts keep source provenance and remain fully editable.
- Existing user-entered fields are preserved unless “Replace fields I already filled” is checked.
- Characters remain reusable assets in My Character Library and, after publication,
  the public Character Library.
