- Remove BOM from all Go source files
- Standardize import ordering and whitespace across handlers and services
- Replace PostgreSQL full-text search with ILIKE pattern matching in post and user repositories
- Enhance JPush client with TLS transport, rate limit monitoring, and simplified API
- Refactor PushService to include userID in device management methods
- Add MaxDevicesPerUser limit and extract helper functions for push payload construction
