Add a FileWriter-compatible per-source binary recorder: native-type encode
and TypeDescriptor mapping, FileWriter header serialization, subset/quantized/
ACCUMULATE row serialization, and push-thread double-buffer flush with size-cap
rotation, keep-N pruning, fdatasync cadence, disk-free and staging-overflow
guards. Covered by 12 GTests; full suite (83) green.
