Proposed fix: [Prebuilt Docker/eval images] `import chromadb`/`import hnswlib` dies with SIGILL (Illegal instruction) on hosts without AVX-512 — native wheel built for the image-build CPU; tests crash

Recommended action: Probe the import in the container and, if it fails, reinstall from source on the target host: pip install --no-binary=hnswlib,chroma-hnswlib --force-reinstall hnswlib chroma-hnswlib; or build images with portable flags / on the oldest target CPU; pin runners to a consistent CPU family. Option: Rebuild the native package from source on the target host [evidence: documented_workaround] Applies when: images with CPU-specific wheels Steps: 1. docker exec <c> python -c 'import hnswlib' (probe) 2. docker exec <c> pip install --no-binary=hnswlib,chroma-hnswlib --force-reinstall hnswlib chroma-hnswlib Expected: import succeeds; tests run Evidence basis (self-declared by the contributing chat client): untested.
