[FEATURE] Preserve hyperlinks/URLs when pasting rich text into the prompt input

Problem

When I paste rich text containing hyperlinks (copied from a Google Doc, email, or webpage where words link to URLs) into the prompt input, the visible words come through but the underlying URLs are silently dropped. The model never receives the links, so I lose them on every paste.

Example: I paste program notes with a linked "newsletter" word and a couple of linked references. After I submit, only the plain words survive and every URL is gone. I then have to hunt down and re-paste each raw URL by hand, or hand over the whole source file instead.

What should happen

Hyperlinks pasted into the input should survive submission so their URLs reach the model. Any one of these would fix it:

• Preserve the link on paste, or
• Auto-convert linked text to Markdown [text](url) on paste so the URL survives as plain text, or
• Add a "paste and keep links / paste as Markdown" option.

This was reported in #39835 (Cowork: Hyperlinks in prompt input are lost on submission) and auto-closed as stale, locked, with no fix. Still reproducing.
