The previous batching sent up to 128 inputs per request but didn't cap total
tokens. On large Hebrew statutes (ספר הליקויים, ספר המבחנים) a single
request exceeded Voyage's 120K-token-per-batch hard cap and failed with 400.
- voyage.embed now pre-computes an estimated token count per input (Hebrew
is ~0.55 tokens/char in voyage-multilingual-2) and emits multiple
requests so each stays under a 90K-token safety margin.
- chunker lowers the per-chunk ceiling to 1500 tokens and updates the
chars→tokens estimate to match the observed tokenizer behavior.
