Fix: replace llama_cpp.server with custom FastAPI server (no mlock, no health check loop)

Fix: install git (required by HF Spaces build system)

Pre-built CPU wheel: pip install in 30s instead of 10min source compile

CPU perf: OpenBLAS build, auto-threads, mlock, batched inference

Pin all deps: python:3.10-slim-bookworm, exact pip versions in requirements.txt

Fix: add build-essential cmake for llama-cpp-python source build

Switch from vLLM to llama-cpp-python (CPU, free HF tier, GGUF Q3_K_M)

Pin to v0.7.3 tag (immutable, cacheable on HF)

Switch to latest tag for faster HF cache hit

Production vLLM deploy: SHA-pinned Docker, pre-flight checks, ai.js client, usage guide
