Enrichment in connectors

[shubhobm]

Summary

This PR strengthens the new enrich path by adding targeted connector tests and ensuring release-time CI runs tests as well.

What changed

1) New/updated unit tests for enrich functionality

• Added tests/unit/connectors/test_enrich_utils.py
  • Verifies deployer normalization to OpenAI for GPT models.
  • Verifies deployer normalization to Together AI for together/* deployers.
• Added tests/unit/connectors/test_garak.py
  • Verifies Garak metric normalization emits publish-compatible dict-shaped results (results.rows).
  • Verifies columnar metric normalization behavior.
• Updated tests/unit/connectors/test_inspect.py
  • Adds coverage for convert_eval_log(..., enrich=True).
  • Adds unresolved benchmark behavior coverage (UnsupportedInspectBenchmarkError path).

2) CI/CD workflow updates for release testing

• Updated .github/workflows/test.yml
  • Tests now run on:
    • pull_request to main (existing)
    • release.published (new)

3) Publish workflow release behavior

• Updated .github/workflows/publish.yml
  • On release, if tag version != pyproject.toml version:
    • auto-aligns version in workflow (poetry version <tag_version>)
    • continues test/lint/typecheck/build/publish in same run
  • Removed blocking "create PR and stop" mismatch behavior.

4) Documentation

• Updated README.md with a Release behavior section documenting:
  • release-time checks
  • tag/version alignment behavior
  • publish flow expectation
