reembedAll

Re-embed every proposition by writing a fresh vector onto each node. Lighter than the interface default (which re-saves the whole view): it SETs only embedding, leaving mentions and other properties untouched. The @VectorIndex-declared index is owned by Drivine, so a same-dimension re-embed needs no index DDL here.

Vectors are computed in memory then written in a single batch in one transaction — sized for ~10–50K propositions. A larger store would want chunked / periodic-commit writes to bound the transaction; not implemented until a store that big exists.
