[Feature]: Add Copy Path and Copy Relative Path to the Files panel context menu

[jasperlg]

Before submitting

• I searched existing issues and discussions and did not find a duplicate.
• I am describing a concrete problem or use case, not just a vague idea.

Area

apps/web (Files panel / file tree context menu)

Problem or use case

Right-clicking a file in the Files panel only offers Copy mention and Add to chat.

There is no way to copy the file's absolute path or its workspace-relative path, the way VS Code and other editors do with Copy Path and Copy Relative Path.

Copy mention is useful for the composer, but it is not a filesystem path. I cannot paste it into a terminal, another editor, a ticket, or a chat outside T3 Code.

Current menu on a file such as confection_status_3695.html:

• Copy mention
• Add to chat

Proposed solution

Add two items to the Files panel file context menu:

• Copy Path: copy the absolute filesystem path
• Copy Relative Path: copy the path relative to the project / workspace root

Suggested placement: with the existing copy action, for example:

• Copy mention
• Copy Path
• Copy Relative Path
• Add to chat

Keyboard shortcuts matching VS Code would be a nice follow-up (Cmd+Opt+C / Cmd+Shift+Opt+C on macOS), but the context menu items are the smallest useful change.

Why this matters

This is a daily editor action. I often need a real path after an agent writes or edits a file: open it in another tool, paste it into a terminal, or share it. Today I have to reconstruct the path by hand from the tree, or use Copy mention and then strip it into a real path.

Smallest useful scope

• File rows in the Files panel context menu only
• Copy absolute path
• Copy relative path
• No directory-row changes, no new keybindings, no new server contracts
