feat: V4-3 complete — all 5 pipeline symbols live, end-to-end registry resolution verified

- Fix blob_store.py: use Vercel Blob v12 API (x-vercel-blob-access header, /?pathname= URL)
- Push run_pipeline and composed_pipeline to codifide.com registry
- Verify python3 -m codifide run pipeline_composed.cod --registry https://www.codifide.com works
- Update REGISTRY.md with all 5 symbol identities
- Mark V4-3-2 and V4-3-5 complete in tasks.md
