Method encode_batch

nodedb-vector/src/quantize/pq.rs:140–148

Batch encode all vectors into a contiguous byte array. Charges `m * vectors.len()` bytes to the governor budget (if set) before allocating the output buffer. The guard is released at the end of this call — the buffer itself remains alive.
