8a5dc38a58 fix: ensure super.stop() is called exactly once in CanalRabbitMQProducer (#5578) 
Previously super.stop() was called both inside the try block and after
the catch blocks. On success it was invoked twice; on IOException it was
never reached. Move super.stop() to a finally block so it executes
exactly once regardless of whether close() succeeds or fails.

5110cfd49d fix: close HttpClient after binlog download to prevent resource leak (#5579) 
BinlogDownloadQueue.download() creates a CloseableHttpClient for each
download but never closes it. Over time this exhausts connection pool
resources. Wrap the HTTP execution in a try-finally block to ensure the
client is always closed.

69a06dba09 fixed issue #5517: H2 database field type error causing 'Value too long for column' exception 
- Changed meta_snapshot.data from longtext to CLOB in H2 schema
- Changed meta_history.sql_text from longtext to CLOB in H2 schema
- H2 database doesn't recognize MySQL's longtext type and converts it to VARCHAR with length limit
- CLOB type supports up to 2GB text data, solving the issue when storing large table structures (>1MB DDL)

f07a075dce refactor(canal/server): 优化程序代码 (#5545) 
- canal server logback.xml 配置增加
   CanalServerWithEmbedded 单独日志配置，流量非常大的情况下，getMessages/ack等日志量非常大
   日志刷盘太快也影响性能，占磁盘空间。用户可以根据需要单独调整日志级别。默认是INFO

- TableMetaCache 锁的范围太大，针对这块做了代码逻辑优化。以下场景影响性能：
   - 当用户关闭tsdb.enable=false, 分库分表数量非常多回查次数很多；
   - 每张表有四五百列甚至更多，里面的集合容器提前初始化，减少扩容的次数；

- DatabaseTableMeta 标记一个内存不安全的地方，以后看情况优化掉
	使用MemoryTableMeta在内存区记录表元数据，当分库分表数量非常多，表结构非常复杂非常吃内存，容易OOM

5a5e60d371 feat(canal/adapter): adapter支持prometheus暴露jvm指标 (#5549) 
- adapter 默认提供prometheus暴露JVM指标

- 指定 maven-antrun-plugin 未指定版本号，默认是 3.0.0，但是配置中使用 <tasks> 标签，编译报错。
   - 降级版本号，显式指定 1.8 版本
   - 或者把配置中的 <tasks> 标签改成 <target>

50a570290a fix(canal/client-adapter): 修复adapter插件重试错误缺陷 (#5427) 
* fix(canal/prometheus): 修复延迟指标的缺陷

-【缺陷描述】
   Admin控制台修改canal.properties配置后，Server自动进行重启，在Grafan上观测到同步实例的PUT/GET/ACK延迟居高不下。

-【原因定位】
   源库心跳正常触发，MemoryStoreWithBuffer正常推进位点，profiling 正常统计，但是延迟指标依然是越来越来越高。Prometheus调用collect接口采集到的exec time时间始终是固定不变的。经debug排查到StoreCollector采集器内存hold的StoreMetricsHolder与CanalInstance实例中的引用已经不同啦，CanalIntance重启时已经被重建过一份新的实例，但是StoreMetricsHolder却没有保存到内存Hold中。原因是Map.putIfAbsent调用引起。

-【修复效果】
- 修复后，重启Server心跳正常推进，延迟瞬间降下来。梳理其他Collector代码都是调用Map.put，只有这里使用putIfAbsent可能是粗心导致吧。修复效果

* fix(canal/client-adapter): 修复adapter插件重试错误缺陷

-【缺陷描述】
  adapter运行期间，针对server或者Instance进行过一次重启或者断网测试，发现adapter通过client拉取数据报错以后持续打印错误日志，永远不得恢复。虽然adapter processor 针对错误有重试逻辑，但是client的tcp连接已经发生中断，且无法恢复。

-【问题定位】
  adapter processor 针对错误的处理比较粗，需要细分是从上游get message报错，还是下游sync data报错？
  如果是 get message报错，特别是tcp 断开，需要跳出重试，重新尝试重连。如果是下游 sync data 报错，再考虑重试写入。下游插件开发者自行保证连接重连机制、写入幂等。框架只提供重试。

- 说明：顺带更新一下 .gitignore 文件
