…LayerNormalization SimplifiedLayerNormalization is RMSNorm and reuses the existing RMSNormalization handler. SkipSimplifiedLayerNormalization adds the residual (input + skip), RMS-normalizes over the last axis and scales by gamma, optionally emitting input_skip_bias_sum; ORT (>=1.19) does not apply the optional bias for the simplified variant, so it is ignored. Validated against onnxruntime (output) and numpy (RMSNorm); bit-close. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

SimplifiedLayerNormalization (RMSNorm; reuses the RMSNormalization handler) and SkipSimplifiedLayerNormalization (residual input+skip then RMSNorm*gamma, optional input_skip_bias_sum output; ORT >=1.19 ignores the optional bias for the simplified variant -- matched empirically). Validated bit-close vs onnxruntime/numpy across shapes; no node-suite regression; clippy+fmt clean. Part of com.microsoft contrib-op coverage for ORT-exported LLMs.
