Add Space Bunny Alpha to Auto Free and remove delisted Ling 3.0 Flash VL

[chrarnoldus]

Summary

Updates the kilo-auto/free candidate pool in apps/web/src/lib/ai-gateway/models.ts:

• Removed inclusionai/ling-3.0-flash-vl:free: OpenRouter's /api/v1/models no longer lists it. The other existing models (poolside/laguna-s-2.1:free, nvidia/nemotron-3-ultra-550b-a55b:free, dots-studio/dots-3-note-preview:free, nex-agi/nex-n2.5-pro:free) are still listed and stay in the pool.
• Added stealth/space-bunny-alpha (Space Bunny Alpha). It is listed on OpenRouter at $0 prompt and completion pricing and already passes isFreeModel through the stealth/*-alpha rule.
  • Weight 1, the same as the other models. Each of the 5 candidates gets about 1/5 of Auto Free traffic.
  • Reasoning { enabled: true, effort: 'high' }, the same as the other models. OpenRouter lists high in this model's supported_efforts.

At request time, getAutoFreeCandidates still includes only non-exclusive models that appear in the OpenRouter models cache. If a model is delisted later, it drops out of routing automatically. This PR also removes the stale entry from the static list.

Tests

models.test.ts now asserts the updated Auto Free set: high reasoning and weight 1 for every model. The existing isFreeModel and positive-weight invariants cover the new entry.

Verification

• Checked each Auto Free model ID against OpenRouter's live /api/v1/models response.
• Formatting checked with oxfmt. Tests run in CI.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Executive Summary

The incremental change switches Space Bunny Alpha's Auto Free reasoning effort from max to high in models.ts and updates the matching test title and expectation; high is a valid OpenRouterReasoningConfig effort and the assertion set stays consistent with the Auto Free model list.

Status: No Issues Found | Recommendation: Merge

Executive Summary

The incremental change reduces Space Bunny Alpha's Auto Free weight from 8 to 1 with a matching test update; the new model satisfies isFreeModel, its max reasoning config is intentional per the PR description, and no dangling references remain after removing Ling 3.0 Flash VL.

Previous review (commit 8faa46d)

Status: No Issues Found | Recommendation: Merge

Executive Summary

Reviewed the two-file Auto Free model routing update in apps/web/src/lib/ai-gateway/; the weight math (8/12 = 2/3), reasoning config, and removal of the delisted model are consistent with the codebase's existing free-model detection and routing logic, with no high-confidence defects found.
