Only gpt-5 is currently deployed on SAP AI Core. Remove models that
fail with 'no deployment found' errors:
- claude-sonnet-4-6
- gpt-4.1
- gpt-4.1-mini
- gpt-5-mini
This can be reverted once the models are deployed.
When a new push arrives while review-bot is processing, the review
would be posted against a stale commit. This causes noise in the
PR timeline with findings that reference code that no longer exists.
Before posting, re-fetch PR metadata and compare HEAD SHA with the
commit we evaluated against. If they differ, log a warning and exit
successfully — a new workflow run should already be processing the
new HEAD.
