- Modularized handlers into dedicated packages (`gemini`, `claude`, `cli`) for better structure.
- Centralized `ErrorResponse` and `ErrorDetail` types under `handlers` package for reuse.
- Updated all handlers to utilize the shared `ErrorResponse` model.
- Introduced specialization of handler structs (`GeminiAPIHandlers`, `ClaudeCodeAPIHandlers`, `GeminiCLIAPIHandlers`) for improved clarity and separation of concerns.
- Refactored `getClient` logic with additional properties and better state management.
Refactor `translator` package by modularizing code for `claude` and `gemini`
- Moved Claude-specific logic (`PrepareClaudeRequest`, `ConvertCliToClaude`) to `translator/claude/code`.
- Moved Gemini-specific logic (`FixCLIToolResponse`) to `translator/gemini/cli` for better package structure.
- Updated affected handler imports and method references.
Add comprehensive package-level documentation across key modules
- Introduced detailed package-level documentation for core modules: `auth`, `client`, `cmd`, `handlers`, `util`, `watcher`, `config`, `translator`, and `api`.
- Enhanced code readability and maintainability by clarifying the purpose and functionality of each package.
- Aligned documentation style and tone with existing codebase conventions.
Refactor API handlers and translator modules for improved clarity and consistency
- Standardized handler struct names (`GeminiAPIHandlers`, `ClaudeCodeAPIHandlers`, `GeminiCLIAPIHandlers`, `OpenAIAPIHandlers`) and updated related comments.
- Fixed unnecessary `else` blocks in streaming logic for cleaner error handling.
- Renamed variables for better readability (`responseIdResult` to `responseIDResult`, `activationUrl` to `activationURL`, etc.).
- Addressed minor inconsistencies in API handler comments and SSE header initialization.
- Improved modularization of `claude` and `gemini` translator components.
Standardize configuration field naming for consistency across modules
- Renamed `ProxyUrl` to `ProxyURL`, `ApiKeys` to `APIKeys`, and `ConfigQuotaExceeded` to `QuotaExceeded`.
- Updated all relevant references and comments in `config`, `auth`, `api`, `util`, and `watcher`.
- Ensured consistent casing for `GlAPIKey` debug logs.
- Centralized `getClient` logic into a dedicated function to reduce redundancy.
- Moved proxy initialization to a new utility function `SetProxy` in `internal/util/proxy.go`.
- Replaced `Internal` handler with `CLIHandler` in `server.go` for improved clarity and consistency.
- Removed unused functions and redundant HTTP client setup across the codebase for better maintainability.
