woogiandCursor 82a48d99cf Add scoped Agent-mode pipeline as experimental Classic fork.
Wire specialist waves, Brain consolidation, and Classic-compatible reports so Agent mode can run end-to-end via OpenRouter without changing the default Classic path.

"""
main.py - Thin FastAPI app: upload a PDF, run the pipeline, return the report.
Run from the project root:
uvicorn backend.main:app --reload
The pipeline is synchronous and can take minutes on a large set; for a single
architect checking one set at a time that's fine. Move to a job queue if this
ever needs concurrency.
