inferencelayer 0.2.3

# Standalone, cross-vendor (Metal/Vulkan/DX12/GL) inference engine on wgpu + hand-written WGSL
# kernels, with a pure-Rust CPU fallback. LFM2/Qwen3 generation, the encoder family (BERT, XLM-R,
# ColBERT, Qwen3-embed, SigLIP, CrossEncoder), sharded fleet serving, and grammar-constrained
# decoding. Extracted from osfkb "crates/lfm2-wgpu" (history preserved); no OSFKB deps — it builds
# and benchmarks standalone. Correctness oracle = the candle LFM2 reference.
