[BUG] File links in Claude Code panel non-functional - regression from v2.1.4 fix

Preflight Checklist

What's Wrong?

File links rendered in the Claude Code chat panel (VS Code extension) are not clickable. They appear visually as hyperlinks but clicking them does nothing - no file opens, no navigation occurs.

This appears to be a regression. Issue anthropics/claude-code#10846 was reportedly fixed in v2.1.4 but the problem persists in v2.1.92. Issue anthropics/claude-code#16056 describes the same behavior on macOS and was also closed without a permanent fix.

What Should Happen?

Clicking a file link in the chat panel should open that file in the VS Code editor, the same way clicking a file link in a regular markdown file does.

Error Messages/Logs

"This is a single bug report" - check it, it is
"I am using the latest version" - check it only if you've confirmed 2.1.92 is the latest. You can verify by checking the Extensions panel in VS Code.

Steps to Reproduce

To reproduce

Open Claude Code in the VS Code panel
Ask Claude to reference a file - it will render something like [filename.md](path/to/filename.md)
Click the link
Nothing happens
