[Feature] Record a demo flow

Is your feature request related to a problem? Please describe.
Need a way to record a step-by-step demo flow in VS Code so common actions can be replayed consistently without manually performing them live each time.

Describe the solution you'd like
Add a recording mode that captures editor actions such as opening a file, creating a new file, and appending or editing text, then stores them as a reusable demo script or sequence. The recording should make it easy to build a narrated demo workflow from real actions performed in the editor.

Describe alternatives you've considered
Manually preparing files and repeating the same actions each time, or relying on static screenshots/video captures instead of an interactive demo workflow.

Additional context
Useful recorded actions could include:

• Open file
• Create file
• Append text
• Insert or replace text
• Save file
• Navigate between files
• Basic pause/wait steps

This would help create repeatable demos with minimal setup.
