feat: wikilink pills in message bubbles, noteList context injection

- Render [[wikilink]] reference pills inside sent message bubbles
  with type-colored badges; clicking a pill opens the note
- Add noteList (filtered note list titles, max 100) and noteListFilter
  to the structured context snapshot sent to the AI
- Thread noteList/noteListFilter from App → Editor → EditorRightPanel → AiPanel
- Store references in AiAgentMessage for display in chat history
- Add tests for reference pill rendering and noteList context
