feat: v0.2.2 — plugin refactor, i18n, outline tracking, formatTable, code title, fr locale

## Added
- French (fr) locale with 60+ translations
- Outline panel scroll tracking with active heading highlight
- exec('formatTable') for auto-aligning Markdown table columns
- Code block title rendering via ```js title=hello.js```
- Escaped pipe \| support in table cells
- Custom block token fallback rendering as <div>
- Gutter incremental DOM update (no more full innerHTML)
- 694 tests (+10)

## Changed
- All 6 preset plugins refactored to closure-based state (no this pollution)
- shortcutHelp plugin now i18n-aware (shortcut labels follow locale)
- Context menu labels (Cut/Copy/Paste/Select All) i18n-translated
- Warm theme now has progressBg + closeHoverBg fields
