What this PR does / why we need it:

Improves speed of embedding transformation so static artifacts are loaded at build time.

Enables loading models, lookup tables, and other static resources once at server startup instead of per-request, improving performance for real-time inference.

Changes

  • Core: Adds load_static_artifacts() function to feature server with FastAPI lifespan integration
  • Template: Updated PyTorch NLP template with static_artifacts.py module and pre-loaded artifact usage
  • Tests: Added 6 comprehensive unit tests covering success, error handling, and persistence
  • Docs: Added static artifacts section to Python feature server documentation
