当前 proxy 的 auto-renew 机制使用一个短 invisibleTime（默认 60s），然后通过周期性 changeInvisibleTime RPC 来续期。这带来三个问题：handle 映射的内存开销与并发复杂度、proxy 崩溃后短 handle 过期导致重复消费、以及持续 RPC 续期的网络开销。本 PR 引入 enableGrpcChannelReceiptHandleRenew 配置开关，关闭后不再周期性续期，改用 consumer group 的 consumeTimeoutMinute 作为初始 invisibleTime，从根本上避免了 proxy crash 导致的重复消费。 -- This is an automated message from the Apache Git Service.
