* feat(oauth): add gemini-3.7-flash models with reasoning tiers for antigravity
Support gemini-3.7-flash and its thinking tiers (low/medium/high) for antigravity and agy providers.
- Define public models, pricing, modelSpecs, and CLI tool definitions
- Map tiers to live upstream id gemini-3.7-flash-tiered
- Configure defaultThinkingBudget (low: 1024, medium: 8192, high: 32768)
- Allow executor fallback on upstream 404 and 5xx errors
- Add unit tests in antigravity-model-aliases.test.ts
* fix(oauth): expose gemini-3.7-flash as one callable antigravity/agy model
Upstream (fetchAvailableModels on daily-cloudcode-pa) only accepts the single
upstream id gemini-3.7-flash-tiered; the high/medium/low suffixed tier ids
404. Registering all four as distinct public model ids violates the base
#3696 uniqueness invariant (no two ANTIGRAVITY_PUBLIC_MODELS entries may
resolve to the same upstream id). Collapse to the single live gemini-3.7-flash
public model (aliased to gemini-3.7-flash-tiered) and drop the tiered specs,
pricing, free-catalog and CLI entries accordingly, keeping the leading public
model order (Gemini 3.6 tiers first) intact.
