Narrow this session's memory to one project: name='' scopes recall, the wake bundle, self-notes and the default namespace for new facts to project::* (identity and conventions always ride along). Returns the narrowed bundle right away. name='' widens back to the whole account. Sticky for the session and across reconnects; bind_agent is unaffected. Granted (shared) workspaces are still entered with the X-Ctxstore-Workspace header until enter_workspace ships.
