## Description Backport apache/iotdb#18224 (ea0b0099227a850254040ab87436eb5bbd092d60) to dev/1.3. The conflict resolution adapts the fix to the 1.3 APIs while preserving its reliability changes: - isolate each async TsFile and companion-file handoff in a unique transfer directory; - deduplicate scanner entries and keep standalone TsFiles discoverable; - retry cleanup without letting one failed deletion skip the remaining companions; - clear pending/loading state correctly across active-loader restarts; - release buffered load memory on abort/cleanup paths. ### Verification - [x] Related DataNode unit tests: 12 tests, 0 failures - [x] Checkstyle and Spotless checks - [x] Integration-test sources compile on dev/1.3 - [ ] The targeted IT could not start locally because the existing integration-test template-node mixed incompatible cached TsFile/ANTLR artifacts (TSEncoding.OBJECT NoSuchFieldError; ANTLR 4.13.2 vs 4.9.3). The failure occurred during ConfigNode/DataNode startup, before the test method ran. <hr> This PR has: - [x] been self-reviewed. - [x] added comments explaining non-obvious intent. - [x] added or updated unit tests for the changed paths. - [x] added an integration test. <hr> ##### Key changed/added classes - ActiveLoadUtil - ActiveLoadDirScanner - ActiveLoadPendingQueue - ActiveLoadTsFileLoader - LoadSingleTsFileNode - LoadTsFileScheduler -- This is an automated message from the Apache Git Service.
