Full document, spreadsheet, slideshow, and diagram tooling
feat: command palette (Cmd+K), row/col insert/delete, context menu, virtual scroll
Command palette (Cmd+K / Ctrl+K):
- Works on all 3 pages (landing, docs, sheets)
- Fuzzy search across documents + contextual actions
- Keyboard navigation, category grouping, shortcut badges
Row/column insert/delete (#113):
- Insert row above/below, insert column left/right
- Delete row, delete column
- Formula references automatically adjusted (handles ranges, absolute refs)
- 47 tests for row-col-ops
Context menu wiring (#149):
- Right-click on cells: cut/copy/paste, insert/delete row/col, clear, notes
- Right-click on row headers: insert/delete row
- Right-click on column headers: sort, insert/delete column
Virtual scrolling wired (#146):
- Only renders visible rows + 5-row buffer
- Spacer elements maintain scroll height
- RAF-debounced scroll listener
69 new tests, 2048 total passing.
Closes #52, #113, #146, #149
