fix(deploy): use hf CLI (huggingface-cli removed in hub 1.x) and pass HF_TOKEN; exclude .env from space upload

fix: point backend URL to HuggingFace Spaces and fix deploy workflow

fix: target Vercel bio-nexus project by id, run deploy from repo root (project rootDirectory avoids path doubling), correct scope

fix: scope Vercel CLI to team owning bio-nexus project; set NEXT_PUBLIC_API_URL in CI; make redundant Render hook non-fatal

Add Render Blueprint, GitHub Actions auto-deploy, revert to CORS fix, local startup scripts
