refactor: decompose Editor.tsx, NoteList.tsx, Sidebar.tsx — CodeScene hotspots (#126)
* refactor: decompose Editor.tsx into focused subcomponents and hooks
Extract from the monolithic Editor component (cc=35, 213 LoC, score 7.82):
- useDiffMode hook: diff state + toggle/commit-diff handlers
- useEditorFocus hook: new-note focus event listener
- editorSchema: WikiLink spec + BlockNote schema (module-level)
- SingleEditorView: BlockNote editor + suggestion menus
- EditorContent: breadcrumb bar + diff/editor/loading views
- EditorRightPanel: AI chat / Inspector panel switching
- suggestionEnrichment util: shared enrichment logic (eliminates duplication)
Editor.tsx is now 10.0 code health (was 7.82). All 25 existing tests pass.
