Forward-merge triggered by push to branch-25.02 that creates a PR to keep branch-25.04 up-to-date. If this PR is unable to be immediately merged due to conflicts, it will remain open for the team to manually merge. See forward-merger docs for more info.

Avoid a bug which causes a batch of trees in the BATCH_TREE_REORG implementation to be labeled as complete (all having reached leaf nodes) when they are not. In the best case, this causes a crash when invalid shared memory is accessed. In the worst case, trees will silently contribute incorrect values to the final output.

This workaround simply disables BATCH_TREE_REORG by remapping BATCH_TREE_REORG to TREE_REORG in the C++ layer. The fundamental issue should be fixed through promotion of experimental FIL to default.
