When the next poll slot is occupied, store the free slot found by the search in the event and advance the hint from that slot. Otherwise the readiness check uses the occupied slot and skips replacement worker output. Direct insertion and both removal paths already use the matching slot.

When worker replacement leaves the next poll slot occupied, FPM registers a descriptor in a different free slot but keeps the occupied index. The poll backend now records the slot it used, so readiness dispatch continues capturing worker output. Direct insertion and both removal paths already use the matching slot.
Found during code review and reproduced with PHP 8.4 FPM on Linux. The regression requires Linux's pipe-EOF ordering to exercise slot search. The separate queue traversal defect is handled in php#25154.
