main.py  —  server entry point for Phase 4b
Imports infer (registers all core routes) then retrieval (registers /retrieve),
then starts uvicorn. This avoids the circular-import problem that occurs when
infer.py tries to import retrieval.py while retrieval.py imports from infer.py.

Run with:
    conda activate claimcheck
    cd C:\\Users\\1\\buss305-project\\claim-evidence-checker
    python src\\main.py

Port:
    Local: 8000 (default)
    HuggingFace Spaces: 7860 (set via PORT environment variable)
