When _OverwriteFiles._deleted_entries() creates DELETED manifest entries, it now sets snapshot_id to the current (deleting) snapshot's ID instead of retaining the original INSERT snapshot's ID. This aligns with the Iceberg spec which states that for DELETED entries, snapshot_id should be the snapshot in which the file was deleted. The existing _DeleteFiles._compute_deletes() already handled this correctly. Signed-off-by: Sotaro Hikita <bering1814@gmail.com>

Rationale for this change
When _OverwriteFiles._deleted_entries() creates DELETED manifest entries, it now sets snapshot_id to the current (deleting) snapshot's ID instead of retaining the original INSERT snapshot's ID.
Closes #3236
According to the Iceberg spec (Manifest Entry Fields),
snapshot_idfor a DELETED entry (status=2) should be the snapshot ID in which the file was deleted. However,_OverwriteFiles._deleted_entries()was copying the original entry'ssnapshot_id(from the INSERT snapshot) into the new DELETED entry.This caused downstream consumers that filter manifest entries by
snapshot_id(e.g. Iceberg Java'sIncrementalChangelogScan) to silently miss DELETED files, breaking CDC pipelines.Are these changes tested?
