Browse Source 
Step 55: WelcomeScreen (actions, recent files, tips, visibility) - 7/7 tests
Step 56: ElispCommandBuilder + MockEmacsConnection (escaping, daemon lifecycle) - 6/6 tests
Step 57: BufferManager (multi-file open/close/switch, language/modified tracking) - 7/7 tests
Step 58: EditorMode (per-language indent, comment toggle, bracket pairs, snippets) - 8/8 tests
