[#969] Refactor: Optimize the request rate limiting for ModelRequestRateLimi…

refactor: update ClaudeMessageSource struct to include optional Url field and adjust media source handling in relay-claude #993

Refactor: Optimize the token bucket algorithm, specifically the New method in common/imiterlimiter.go.
Solution: Remove Redis ping. When printing exceptions, use SysLog to print and add additional logging information.

Reason: The original steps 1 and 3 in the redisRateLimitHandler method were not atomic, leading to poor precision under high concurrent requests. For example, with a rate limit set to 60, sending 200 concurrent requests would result in none being blocked, whereas theoretically around 140 should be intercepted.
Solution: I chose not to merge steps 1 and 3 into a single Lua script because a single atomic operation involving read, write, and delete operations could suffer from performance issues under high concurrency. Instead, I implemented a token bucket algorithm to optimize this, reducing the atomic operation to just read and write steps while significantly decreasing the memory footprint.

fix: wrong field for Claude (OpenAI Upstream)

fix(relay): 优化数据流处理

- 移除了 bufio 的无效使用
- 在 StreamScannerHandler 中增加了初始和最大缓冲区大小的常量设置
- 调整 StreamScannerHandler 中缓冲区大小，避免出现token too long报错

fix: .env文件配置DEBUG=true等参数不起作用的fix

feat: add xAI channel
