[BEZALEL][Epic-001] The Forge CI Pipeline — Gitea Actions + Smoke + Green E2E

- Add .gitea/workflows/ci.yml: Gitea Actions workflow for PR/push CI
- Add scripts/smoke_test.py: fast smoke tests (<30s) for core imports and CLI entrypoints
- Add tests/test_green_path_e2e.py: bare green-path e2e — terminal echo test
- Total CI runtime target: <5 minutes
- No API keys required for smoke/e2e stages

Closes #145
