## Description ### Problem When `TsFileInsertionEventScanParser` reached EOF while producing the final tablet, `prepareData()` closed the parser immediately. The iterator then tried to release the parser-side tablet memory in its `finally` block, which called `forceResize(0)` on an already released memory block and could continuously emit `forceResize: cannot resize a null or released memory block` warnings. ### Changes - Defer parser close at EOF until after the final tablet memory accounting is released. - Keep immediate cleanup in the constructor when a TsFile contains no tablet data. - Strengthen the parser unit test to verify that tablet memory usage is zero before its block is closed. ### Tests - `mvn spotless:apply -pl iotdb-core/datanode` - `mvn -pl iotdb-core/datanode -Dtest=TsFileInsertionEventParserTest test` (21 tests, 0 failures, 3 skipped) <hr> This PR has: - [x] been self-reviewed. - [x] added comments explaining the why and intent of the non-obvious close ordering. - [x] modified an existing unit test to cover the regression. <hr> ##### Key changed/added classes - `TsFileInsertionEventScanParser` - `TsFileInsertionEventParserTest` -- This is an automated message from the Apache Git Service.
