Add Database workflow skills catalog and workflow skill

[BigSimmo]

Summary

• Add .agents/skills/database-skills.md documenting Database-local skills.
• Add .agents/skills/workflows/SKILL.md as an indexed workflow skill reference.
• Add .agents/skills/workflows/agents/openai.yaml companion interface metadata.

Verification

• Confirmed branch base is current origin/main before cherry-picking.
• Cherry-picked commit d22a989 to codex/workflow-skills-main as 1d75bfb containing only the three files.
• Verified git status was clean after commit with only the intended three new files staged/committed.
• Verification not run: full regression suite, as these are metadata/skills-doc-only changes with no runtime impact.

Risk and rollout

• Risk: low — no runtime, clinical, API, database, or UI behavior changes.
• Rollback: revert commit 1d75bfb or close PR if needed.

Summary by CodeRabbit
