Environment

• OS: Windows
• Eclipse Version: 2026-03
• Plugin Version: 0.18.0

Describe the bug
When a project backed by a non-file:// URI scheme (e.g. an RSE remote project
mounted over SSH) is present in the Eclipse workspace, sending a message in the
Copilot Chat view fails and an error is returned instead of a response.

To Reproduce
Steps to reproduce the behavior:

1. Add a remote project to the workspace via RSE (or any other non-file:// provider).
2. Open the Copilot Chat view.
3. Send any message.

Expected behavior
Chat responds normally, ignoring or gracefully skipping workspace folders whose
URI scheme is not file://.
