OpenCADStudio/plugins#901 (comment) - Add HostApi::document_path(tab_id) returning Option<PathBuf>. - Add PluginRequest::DocumentPath and PluginResponse::DocumentPath for out-of-process plugins. - Implement the request in the IPC server and in both V3/V4 plugin-side HostApi proxies. - Implement HostSession::document_path by looking up the tab by id and returning its current_path.
