feat: add file-backed canvas notes

Magic Notes previously supported rich-text records without a paged drawing or PDF annotation workflow. Add the integrated PeopleLib Fabric and Quill editor with flowing text, pen/highlighter, object transforms, images, paper templates, PDF backgrounds with native text extraction, and raster PDF export. Saves are manual; undo/redo remains scoped to an annotation page or Quill mode. Analyze drafts, saved canvases and canvas-source todos with page images and text when the default model supports images, or an explicitly labelled text-only fallback. Keep successful saves when automatic analysis fails and prevent MCP plain-text replacement of canvas records. Move entry bodies and binary assets into local note files with schema 38 migration and verified readback. SQLite retains metadata, indexes, revisions, todos and comments. Backups must coordinate SQLite and the adjacent notes directory while writes are paused or the app is closed; no one-click backup action is included. Show a continuous record stream with independent collapsible record index and AI pane, real first-page thumbnails, and scroll-only record navigation. Open a blank text/canvas composer by default and reset it after creation. Protect unsaved drafts and establish normalized editor baselines after saving so clean records do not prompt again when leaving. Validation: latest recorded focused run passed 149 tests across five files; typecheck, lint and git diff --check passed. The prior user-reported full run passed 4,713 tests before later corrections and UI changes; it is not a full validation of this final snapshot. Tests were not rerun for this commit, as requested; independent systematic review follows the commit. Release note: Create paged notes with handwriting, flowing text and PDF annotations, browse records through thumbnails, and request AI comments with an explicit text-only fallback. Existing notes migrate to local file storage; backups now need both the database and notes directory.
