Obsidian-style [[wikilinks]] for the notes surface. New ext_notes_links
table (source_id, target_id, link_text) with bidirectional indexes.
Backend: _extract_wikilinks() parses [[...]] via split (no regex in
Starlark). _sync_links() on create/update resolves titles to note IDs.
Cascade delete cleans both directions. GET /links/:id and
GET /backlinks/:id endpoints.
Frontend: wikilinks render as clickable links in preview — blue for
resolved, red for unresolved. Clicking resolved navigates; clicking
unresolved creates the note and re-saves source to resolve the link.
BacklinksPanel shows incoming links below editor with click navigation.
Notes package 0.3.0 → 0.4.0.
