- Uniform auth responses remove the session-enumeration oracle: unknown
session and wrong password now return an identical 401 at the API layer and
an identical WS handshake/close; desktop-status and the 503 "not connected"
signal are only exposed after successful auth.
- Session-count cap re-checked after bcrypt.hash so concurrent creates can't
overshoot maxSessions.
- Relay web client reconnect backoff resets only after a successful auth
response (an accept-then-close server no longer defeats the backoff).
- idGenerator comment corrected to match the rejection-sampling; drop unused
recordFailure return value.
- DEPLOY.md: document ALLOWED_ORIGINS for reverse-proxy deployments.
