Generate a Personal Access Token (PAT) for browser-free auth. Requires you
to be logged in already (brainkb_login or brainkb_globus_login). The token is
shown ONCE and never again — copy it and set it as BRAINKB_TOKEN in your
MCP/skill config; then no login or browser is needed until it expires.
`name`: a label so you can tell tokens apart (e.g. 'laptop'). `days`: lifetime
(default 90, server-capped). Treat the returned token like a password.
