Code-review follow-up: the exit-sound/login-complete events are emitted
inline at their transitions, so the _exitSoundPending/_loginCompletePending
fields were set-then-cleared dead code — removed. Added a comment explaining
why TunnelContinue's min-advance is gated on worldReady. No behavior change;
29/29 sequencer tests still green.

TunnelContinue exit gate: minMet requires worldReady (min-continue hold);
maxForce fires unconditionally at MaxContinue (safety-net fallback when
world never loads). This matches spec §3.4.
