feat(ai-gateway): route 70% of Auto Free traffic to Space Bunny

[chrarnoldus]

Summary

• Raise the stealth/space-bunny-alpha Auto Free weight from 1 to 7. With the three other Auto Free models at weight 1, Space Bunny now receives 7/10 = 70% of Auto Free selections (previously 25%).
• When some candidates are filtered out as unavailable, the share is computed over the remaining weights, as before.

Verification

• Updated the models.test.ts weight test to assert the new weights and the 70% share. Tests run in CI.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

The follow-up change lowers the stealth/space-bunny-alpha Auto Free weight from 12 to 7 and updates the test to assert 70%; with the three other models at weight 1 (total 10), selectAutoFreeCandidate gives a consistent 7/10 = 70% share, and no bugs, security issues, or memory-leak risks were found in the changed code.

Status: No Issues Found | Recommendation: Merge

The weight change from 1 to 12 is consistent with the selection logic in selectAutoFreeCandidate (total weight 15, giving a 12/15 = 80% share) and the updated test asserts both the new weights and the 0.8 share correctly; no bugs, security issues, or memory-leak risks were found in the changed code.
