YoVinchen	fef4c239c4	feat(proxy): add streaming SSE transform and thinking parameter support ... New features: - Add OpenAI → Anthropic SSE streaming response transformation - Support thinking parameter detection for reasoning model selection - Add ANTHROPIC_REASONING_MODEL config option for extended thinking Changes: - streaming.rs: Implement SSE event parsing and Anthropic format conversion - transform.rs: Add thinking detection logic and reasoning model mapping - handlers.rs: Integrate streaming transform for OpenRouter compatibility - Cargo.toml: Add async-stream and bytes dependencies	2025-12-01 17:11:23 +08:00
YoVinchen	a35d112cd4	feat(proxy): implement provider adapter pattern with OpenRouter support ... This major refactoring introduces a modular provider adapter architecture to support format transformation between different AI API formats. New features: - Add ProviderAdapter trait for unified provider abstraction - Implement Claude, Codex, and Gemini adapters with specific logic - Add Anthropic ↔ OpenAI format transformation for OpenRouter compatibility - Support model mapping from provider configuration (ANTHROPIC_MODEL, etc.) - Add OpenRouter preset to Claude provider presets Refactoring: - Extract authentication logic into auth.rs with AuthInfo and AuthStrategy - Move URL building and request transformation to individual adapters - Simplify ProviderRouter to only use proxy target providers - Refactor RequestForwarder to use adapter-based request/response handling - Use whitelist mode for header forwarding (only pass necessary headers) Architecture: - providers/adapter.rs: ProviderAdapter trait definition - providers/auth.rs: AuthInfo, AuthStrategy types - providers/claude.rs: Claude adapter with OpenRouter detection - providers/codex.rs: Codex (OpenAI) adapter - providers/gemini.rs: Gemini (Google) adapter - providers/models/: Anthropic and OpenAI API data models - providers/transform.rs: Bidirectional format transformation	2025-12-01 16:01:06 +08:00
