Subject: [PATCH] feat: Add progress reporting for C# language server indexing

- Implement handle_progress function to display indexing progress
- Add window/workDoneProgress/create request handler
- Enable workDoneProgress capability in both window and workspace
- Replace do_nothing handler with proper progress notifications

This should display progress messages during C# project indexing instead of appearing to hang.
