VS Code: Show relative file paths in tool call headers, not just filename

When Claude Code makes tool calls (Edit, Read, Write, etc.) in the VS Code extension, the chat panel only shows the bare filename — e.g., "Edit build-version.ts". The full path is not visible without hovering (and even then, tooltips are inconsistent).

For users working across multiple repositories in a single workspace, this makes it impossible to tell which project a file belongs to at a glance. "Edit build-version.ts" could be any of a dozen repos.

Request: Show the path relative to the workspace root in tool call headers, e.g.:

• Edit ai-gospel-library/src/lib/build-version.ts
• Read cc/speech-server.py

Instead of:

• Edit build-version.ts
• Read speech-server.py

Even better, make it a setting with options: filename, relative, or absolute.

This is especially valuable for users who manage many repos under one workspace root and frequently edit files with the same name across different projects.
