fix(ci): build all AI models in workflow

Fix workflow to build both MiniLM and CodeT5 models by default.

Issue: Workflow was not passing --all flag, so only MiniLM was built by default,
but verification expected both MiniLM and CodeT5 files to exist.

Changes:
- Add --all flag to build command to build both models
- Update cached artifacts check to verify all 3 model files exist
- Add explicit check for codet5-decoder file in verification step
- Add better logging for expected files when cache is invalid

This ensures the workflow behavior matches the verification expectations.
