Change size_t to std::size_t in noise.h, fill Debian compilation issue
- pack QKV and gate/up projections and use fused SwiGLU in the shared Qwen decoder path - use grouped FlashAttention, F16 bucketed KV caches, direct set-rows updates, and CUDA-friendly RoPE/view/set-rows graphs - retain and reuse cloned-reference KV prefixes so repeated server requests prefill only their text suffix - add graph and F16 KV correctness coverage plus fixed-seed request-level CUDA benchmark/parity tooling - document the optimized Higgs runtime controls and reproducible validation flow

Problem
PocketTTS aborts the entire audio.cpp server when long or token-dense prompts overflow the fixed 32,768-node FlowLM prompt graph. The crash occurs while adding per-step key/value cache transfer nodes.
Change
No API, configuration, model, or migration changes are included.
