- Add SmoothAttn/SmoothDownProj hooks and AlphaSearcher in vllm_calibrate_utils for smooth stats collection and alpha search
- Add tools/smooth with vLLM-side smooth calibration runner and weight conversion utility
- Add HY3 smooth config, calibrate/convert/e2e scripts, and docs
- Extend vllm_patch (envs, fused_moe, install) for smooth support

Move SmoothQuant code into a new self-contained package with a shared core/ layer; the vLLM online path and the HF offline convert path now both consume the same algorithm primitives (formulas, QDQ, RoPE/GQA, alpha searcher, smooth stats I/O) instead of carrying ~3000 lines of duplicated implementation across vllm_calibrate_utils and tools/smooth/convert_smooth_weights.py. Patched fused_moe.py now imports from a standalone smooth_moe_inject module deployed by install.sh next to vllm_calibrate_utils.
