feat(antigravity): comprehensive enhancements - model mapping, rate limiting, scheduling & ops

Key changes: - Upgrade model mapping: Opus 4.5 → Opus 4.6-thinking with precise matching - Unified rate limiting: scope-level → model-level with Redis snapshot sync - Load-balanced scheduling by call count with smart retry mechanism - Force cache billing support - Model identity injection in prompts with leak prevention - Thinking mode auto-handling (max_tokens/budget_tokens fix) - Frontend: whitelist mode toggle, model mapping validation, status indicators - Gemini session fallback with Redis Trie O(L) matching - Ops: enhanced concurrency monitoring, account availability, retry logic - Migration scripts: 049-051 for model mapping unification
