#67351) ### What problem does this PR solve? Issue Number: None Related PR: None Problem Summary: During merge-on-write cloud schema changes, the delete-bitmap temporary tablet copied stale rowset metadata from the real shadow tablet. Its version tracker could select a compacted stale edge that was absent from the active rowset map, causing schema change to fail with a rowset capture error under concurrent writes and compaction. Clear only the copied stale rowset metadata before constructing the temporary tablet so its tracker is built exclusively from active schema-change output and incremental rowsets, without altering the source tablet or shared delete-bitmap cache. ### Release note Fix cloud merge-on-write schema changes that could fail during concurrent writes and compaction. ### Check List (For Author) - Test: Unit Test - `./run-be-ut.sh --run --filter=CloudSchemaChangeJobTest.* -j 48` - `./build.sh --be -j 48` - Behavior changed: Yes. Cloud schema change temporary tablets no longer inherit stale rowset metadata. - Does this need documentation: No
