Record a pipeline in pipeline-keys.bin at its fast link, not only when its optimised build ends.

A session of 2026-11-13 met 46 pipelines late in adult Kokiri Forest (145 draws left out, mesh pipelines usable after up to 782 ms) and ended about 2 s later: the records waited for the optimised builds, and 23 of the 46 never reached the file, so the shared pipeline list folded from it would have missed them. A pipeline is now recorded as soon as a draw can use it.
