demo: regression fail (baseline comparison)

[geminimir]

Enables baseline comparison and removes the required disclaimer from one record to simulate a regression.

Expected:

• Check runs in gate mode with baseline-ref: origin/main and regress: true
• Fails with new violations vs baseline
• HTML report artifact: promptproof-report.html
• PR comment shows regression count and metrics

How to green it:

• Restore the removed disclaimer line and re-run
• Or refresh the baseline after a green run on main (snapshot promotion)
