2dda168b19 perf(db): switch pool recycling method from Verified to Fast 
Verified 每次取连接都会额外发 SELECT 1 验证；Fast 直接复用，
依赖 tokio-postgres 在使用时自然报错，由 get_conn 的退避重试兜底。

54f7bd481a perf(db): replace fixed 2s retry with exponential backoff + jitter 
get_conn 现在按 base*2^attempt + 随机 jitter 退避（200ms 起步），
避免连接池抖动时多请求同步重试形成惊群。

104ff427f9 perf(db): add exponential backoff retry helper with tests 
引入 src/db/retry.rs，提供 base * 2^attempt + jitter 的退避序列，
取代 pool.rs 中固定 2s 重试。MAX_RETRIES 将在下一个提交中被 get_conn 使用。
