Editing text in the prompt input can now feed a keystroke recorder, excluding pasted text

What

The core key handler for the prompt input box now sends each text-changing edit to a recorder, capturing the text and cursor state before and after the edit, whenever recording is active. Paste-like automatic insertions are excluded from this via a new skip flag.

Why

This lays groundwork for capturing keystroke-level editing history in the input box, while deliberately not recording pasted content.
