invalidateSession previously ignored its argument, so a stateless JWT
stayed valid until exp after logout (audit finding B5). createSession
now embeds the minted session.id in the token as jti; invalidateSession
records that jti in an in-memory denylist with expiry-based pruning, and
validateSession rejects denylisted (and jti-less, failing closed)
tokens. The denylist is per-process — the single-process limitation and
the shared-store upgrade path are documented in session-denylist.ts.
