chore(release): sync API dumps for 0.32.0 + validate transformer-core

apiCheck was red: llm-core.api still listed the NN primitives that the 0.31.1
transformer-core extraction moved out, and transformer-core had no API
validation at all — so those public types were tracked nowhere.

- Add binary-compatibility-validator to transformer-core; apiDump creates
  transformer-core/api/jvm/transformer-core.api (the 30 moved primitives:
  attention, KV-cache family, embedding, norms, RoPE, FFNs, linear projection).
- Regenerate llm-core.api (drop the moved primitives — they're now tracked in
  transformer-core, not lost).
- llama.api: + convertLlamaWeightsPacked (the 0.32.0 NATIVE_OPTIMIZED feature).

apiCheck now passes.
