jpmschweitzerandClaude Opus 4.6 cf8a4e37d8 fix(engine): offload Gemma to GPU by setting n_gpu_layers=999 (#833)
LlamaModelParams::default() sets n_gpu_layers=0, so even with --features
rocm the model ran entirely on CPU at ~19 t/s. Setting n_gpu_layers to a
large sentinel value asks llama.cpp to offload every layer the model
has; llama.cpp clamps to the real count (27 for Gemma 2 2B). Observed
throughput jumps from 19 t/s to 74 t/s on an RX 9070 once the ROCm
binary is also compiled for gfx1201 (see tooling commit).

Also adds server/sr-voice/.gitignore so locally-built binaries don't
sneak into the worktree. Release binaries ship out-of-tree per #850.

jpmschweitzerandClaude Opus 4.6 1b58d8f949 feat(engine): add sr-voice LLM inference service for NPC voice pipeline
Standalone Rust crate wrapping llama-cpp-2 for GGUF model inference.
Persistent HTTP server architecture — model loaded once, requests
processed sequentially, zero CPU contention by construction.

Subcommands: serve (load model, listen), generate (single prompt),
batch (JSONL), benchmark (5-run average). Makefile targets for
build/serve/run/stop workflow.

Spike 1 validated: Gemma 2B Q4_K_M at ~16 t/s CPU, 4 cultures
tested (Krenn, Ireland, Shek'na, Aranthi), composition-engine
oath injection mechanism proven. GO for Spike 2.
