What's Wrong?

File references persist even after clearing conversation
No way to remove them, only hide

Steps to Reproduce

Steps to Reproduce:

Open a project in VS Code that contains a package.json file
Open the Claude Code extension panel
Reference a file using @package.json or by dragging a file into the prompt while holding Shift
Send a message that uses that file reference
Complete the conversation or use /clear to clear the conversation
Observe that the file reference (package.json) still appears in the input bar footer
Attempt to start a new conversation using "Open in New Tab" or "Open in New Window" from Command Palette
Observe that the file reference still persists

Expected Behavior:

Clearing a conversation (/clear) should remove all file references from the input bar
Starting a new conversation should provide a clean slate with no file references
There should be an X button or similar control to manually remove file references from context

Actual Behavior:

File reference remains pinned in the input bar footer
Only option available is to "hide" the reference, not remove it
Reference persists across new conversations and cleared sessions
No X button or removal option exists
