Method build_codec_dispatch

nodedb-vector/src/collection/codec_build.rs:54–63

Build a codec-dispatched index over all current vectors using the requested quantization. Replaces any existing dispatch index for this collection. Idempotent. Returns a reference to the new index, or `None` if the quantization tag is not supported (falls back to per-segment Sq8/PQ paths) or there are no vectors to train on.
