 - Extension UI dialogs (`ctx.ui.select()`, `ctx.ui.confirm()`, `ctx.ui.input()`) now support a `timeout` option that auto-dismisses the dialog with a live countdown display. Simpler alternative to `AbortSignal` for timed dialogs.
 - Extensions can now provide custom editor components via `ctx.ui.setEditorComponent((tui, theme, keybindings) => ...)`. Extend `CustomEditor` for full app keybinding support (escape, ctrl+d, model switching, etc.). See `examples/extensions/modal-editor.ts`, `examples/extensions/rainbow-editor.ts`, and `docs/tui.md` Pattern 7.
 - `ExtensionRuntime` interface for shared runtime state and action methods
