This commit introduces several architectural improvements and optimizations across the codebase: - **Performance & Reliability**: - Implemented Redis pipelining in `ConversationCache.CacheMessage` to reduce network round-trips. - Added a circuit breaker to the JPush client to prevent cascading failures. - Introduced batch deletion and batch member addition capabilities in repositories. - Added message idempotency support using `client_msg_id` and a Redis-based cache. - Optimized WebSocket handling with connection limits (total and per-user) and improved error logging. - **Code Refactoring**: - Refactored `Router` to use a `RouterDeps` struct, simplifying the constructor and improving maintainability. - Unified model ID generation logic using new `id_helper.go` (supporting UUID and Snowflake). - Standardized JSON serialization/deserialization in models using `json_helper.go`. - Refactored DTO conversion logic, specifically for `UserResponse` (using functional options) and `Report` responses. - Removed redundant/deprecated DTOs like `PostDetailResponse` and `TradeItemDetailResponse`. - **Cache Improvements**: - Enhanced `LayeredCache` with `SetRaw` to avoid double-encoding when promoting values from Redis to local cache. - Added `DeleteBatch` support to the cache interface. - **Other Changes**: - Cleaned up `config.go` by removing redundant default values and explicit environment variable overrides. - Improved WebSocket registration flow to handle connection limits gracefully.
