Fused Gelu activations emitted by ORT-optimized / GenAI transformer exports, lowered onto existing element-wise primitives: BiasGelu(x, bias) = erf gelu of (x + bias) FastGelu(x, bias?) = tanh-approx gelu of (x + bias) QuickGelu(x) = x * sigmoid(alpha * x) (alpha attr, default 1.702) Validated bit-close against onnxruntime (max |diff| <= 4e-7).

Adds com.microsoft BiasGelu/FastGelu/QuickGelu importer handlers, lowered onto existing element-wise primitives. Validated bit-close (<=4e-7) vs onnxruntime across shapes/bias/alpha; no node-suite regression; clippy+fmt clean. Part of com.microsoft contrib-op coverage for ORT-exported LLMs (complements #2283/#2284).
