[BUG] IDE file context indicator shows stale file after closing it

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)

What's Wrong?

When launching Claude Code in the terminal, the file context
indicator in the bottom-right corner (see screenshot) shows a file that has been
closed in the IDE. The indicator persists across new conversations and does not
update when the file is closed and a different file is focused in Cursor.

What Should Happen?

The file context indicator should reflect the currently
focused file in the IDE. If the previously indicated file has been closed, it
should either show the newly focused file or show nothing.

Error Messages/Logs

Steps to Reproduce

1. Open a file (e.g., README.md) in Cursor
2. Launch Claude Code — the file context indicator appears in the bottom-right

(e.g., "In README.md")

1. Close that file in Cursor
2. Focus on a different open file
3. Exit Claude Code and start a new conversation
4. The indicator still shows the closed file
