Use greedy decoding: do_sample sampling path fails on fp16 logits in transformers.js 3.8.1; remove temp instrumentation

Instrument adapter (temporary): expose generator + wrapper call counter

Adapter v3: learn expected KV dtypes via try/flip/retry (session metadata unavailable in CDN ORT build)

Add KV dtype adapter: align KV-cache feed dtypes with session input metadata (handles both fp16- and fp32-resolving ORT builds)

Force WASM inference: WebGPU shader-f16 corrupts this fp16 export (verified on-device); WASM output verified correct. Trim max_new_tokens to 160.

Fix generation: remove fp16 I/O shim (config kv_cache_dtype handles it), pin transformers.js 3.8.1, refresh stale cached configs, restore WASM fallback with shader-f16 gate

Shim: only cast when session input metadata expects float16

Add fp16 I/O shim: cast fp32 KV feeds to fp16 and fp16 logits to fp32

Use current Transformers.js 3.x for fp16 KV cache

Require WebGPU for fp16 GPU Mart inference

Use fp16 ONNX with graph optimizations disabled
