Function recover_recursive 

pub fn recover_recursive(
    root_path: Option<&str>,

    register: bool,
) -> Result<()>

Recursively walk a directory tree and recover orphaned sessions for all workspaces found.

This combines the logic of detect_orphaned (finding orphaned workspace hashes and copying sessions to the active workspace) with register_recursive (using the workspace-map filter for fast scanning). Optionally registers recovered sessions in VS Code’s index.
