feat(v2): implement session persistence, file watcher, and markdown viewer
Phase 4 complete (MVP ship): - SessionDb (rusqlite, WAL mode): sessions + layout_state tables, CRUD - FileWatcherManager (notify v6): watch files, emit Tauri change events - MarkdownPane: marked.js rendering with Catppuccin styles, live reload - Layout store wired to persistence (addPane/removePane/setPreset persist) - restoreFromDb() on startup restores panes in layout order - Sidebar "M" button opens file picker for markdown files - New adapters: session-bridge.ts, file-bridge.ts - Deps: rusqlite (bundled), dirs 5, notify 6, marked
