Subject: [PATCH] fix: update undo demo and restore watch build

Replace the outdated no-undo message with the supported undo and redo keyboard shortcuts.

Allow Rollup watch mode to write its generated bundles into the app directory, matching the existing project layout and avoiding the Rollup 4.63 input-inside-output validation failure.

Verified the extension production build, development watcher, all 91 tests, and git diff checks.
