refactor: remove unused PendingClosureDispatch class (#1001)

* refactor: remove unused PendingClosureDispatch class

- Remove `PendingClosureDispatch` class in favor of `PendingAsyncQueueDispatch`
- Add `onConnection()` alias method to `PendingAsyncQueueDispatch` for backward compatibility
- Update all documentation to reference `PendingAsyncQueueDispatch`
- Update test files to use `PendingAsyncQueueDispatch` and correct property references
- Remove dedicated `PendingClosureDispatch` test files

This change simplifies the codebase by using the shared `PendingAsyncQueueDispatch`
class from the Support package, eliminating code duplication while maintaining
the same functionality and API compatibility.

* Update docs and translate

* Remove onConnection method in PendingAsyncQueueDispatch

The onConnection method was removed from PendingAsyncQueueDispatch in favor of using onPool directly. All test cases have been updated to replace onConnection calls with onPool to maintain consistency and avoid method duplication.

* Update docs to use onPool instead of onConnection

Replaces all instances of the onConnection method with onPool in async queue closure job documentation for consistency with the latest API usage.

* Update async queue closure job docs for method naming

Replaces references to `onConnection` with `onPool` in the Chinese documentation for consistency with the API. Adds formatting improvements to the English documentation for better readability.

* Replace onConnection with onPool in async queue docs

Updated documentation to use the onPool method instead of onConnection for specifying queue connections, reflecting API changes and improving consistency in examples and method descriptions.

* Update docs and translate

* Update async queue job docs to use onPool method

Replaces references and documentation for the onConnection method with onPool in all language versions. Clarifies that onPool sets the queue connection name and removes duplicate/alias documentation for consistency.

* Update docs and translate

* 删除 AsyncQueueClosureJob 相关的测试文件以简化代码库

* 添加 AsyncQueueClosureJob 的功能测试，验证 dispatch 方法及其链式调用
