chore: remove __pycache__ from git tracking

fix: flip architecture - Next.js on public port 8000, FastAPI internal on 7860

fix: frontend now displays at root URL - proxy '/' to Next.js, move API info to /api/info, restore next.config.ts, add server/__init__.py

fix: resolve OpenEnv validation errors (missing uv.lock, frontend intercepting API endpoints)

fix: add root endpoint to FastAPI so HF Space shows status instead of 404

feat: production-ready submission - hackathon-winning notebook, timeline blog, 14 bug fixes, reward plots

Fix backend configuration and score clamping bounds

Fix: Resolve all critical backend errors - openenv.yaml YAML corruption, reset route empty body crash, server port mismatch, reward signal for error actions

feat: Finalized OpenEnv CVE Triage Backend integration and completed Hackathon README requirements
