The provisioning docstring claimed the invitee row gets
`last_seen_at = NULL` as the "not yet arrived" discriminator. It does
not: the column is NOT NULL and the INSERT omits it, so it defaults to
datetime('now') — the longer note below already explained this, but the
bullet contradicted it. Rewrite the bullet to state the real behavior
(both timestamps default to now; the pending-invite state lives in the
unclaimed user_invite_tokens row) and note that consumers must treat a
pending-invite row as never-seen. Comment-only; no runtime change.
