A loop started by a far/early car would (a) give up before the REAL car settled at
the barrier, and (b) swallow the real car's pushes (the #polling guard dropped them).
So a confident-but-wrong far-car plate could win, or the intended car get debounced
out after the loop ended — wrong car acted on, right car blocked.
Fix: a push that JOINS a running loop now EXTENDS the deadline (lastPush +
ANPR_POLL_WINDOW_MS) instead of being dropped, capped at start + ANPR_POLL_MAX_MS
(30s) so a continuously-busy lane can't slide forever. Each tick still pulls a FRESH
frame, so the loop tracks whoever is at the barrier NOW, not the car that started it.
Per-camera sliding deadline in #pollDeadline (cleared with #polling in finally).
+1 test (push mid-poll keeps the loop alive past the initial deadline); 171 server
tests green. New knob ANPR_POLL_MAX_MS documented in the komodo env reference + the
two concurrency guards written up in lane-presence-and-anpr-entry.
