AlinsRan opened a new pull request, #13761: URL: https://github.com/apache/apisix/pull/13761
### Description Follow-up to https://github.com/apache/apisix/pull/13717#discussion_r3662535767. After #12426 moved health checks to `healthcheck_manager`, nothing registers a clean handler any more: `config_util.add_clean_handler()` has no caller outside its own unit test. That makes every `fire_all_clean_handlers()` call a no-op and every `item.clean_handlers = {}` initialization dead weight on each config item. This removes the mechanism uniformly instead of dropping it from one config backend only: - `core.config_util`: drop `add_clean_handler`, `cancel_clean_handler`, `fire_all_clean_handlers` - `config_etcd` / `config_yaml` / `config_xds`: drop the fire sites and the `clean_handlers` initialization - `plugin.lua`: drop the field from the dummy global rule - `control/v1.lua`: drop the field from the routes/services dump - docs: drop the stale `clean_handlers` entries from the control API response samples - `t/core/config_util.t`: drop the test that only covered the removed API No behavior change — the removed code paths were unreachable. ### Checklist - [x] I have explained the need for this PR and the problem it solves - [x] I have explained the changes or the new features added to this PR - [x] I have added tests corresponding to this change - [x] I have updated the documentation to reflect this change - [x] I have verified that this change is backward compatible (if not, please discuss on the [APISIX mailing list](https://github.com/apache/apisix/tree/master#community) first) -- This is an automated message from the Apache Git Service.
