🐛 Bug Fixed

• Fixed an issue where improper configuration of the exponential backoff algorithm caused some coroutines to be unable to acquire locks for extended periods.
• Added timeout control mechanism for the pdo_pgsql coroutine implementation to improve database operation stability.
• Fixed an issue where Domain and Path parameters were specified when clearing a cookie but were not included in the actual response, preventing the cookie from expiring properly.

🐛 Bug 修复

• 修复了因指数退避算法配置不当，导致部分协程长期无法获取锁的问题。
• 为基于 pdo_pgsql 的协程实现增加了超时控制机制，以提升数据库操作的稳定性。
• 修复了在清空 Cookie 时，虽然指定了 Domain 和 Path 参数，但实际响应中未携带这两个属性，导致 Cookie 无法正常过期的问题。
