Debugging is not yet supported via collab

Error message

Debugging is not yet supported via collab

What it means

A guest in a shared (collab) session attempted to start debugging; DapStore's remote path hit an explicit capability guard because launching debug adapters on the host is not implemented for collab participants.

Solutions

1. Run the debug session from the host's own Zed instance instead of as a guest
2. Wait for collab debugging support if on a shared project
