Tests that validate how Iceberg snapshot expiration interacts with tags and branches, demonstrating that refs protect snapshots from expiration and that the `history.expire.max-ref-age-ms` table property can be used to automatically expire refs and their protected snapshots.
Validates that expire_snapshots can break the snapshot ancestor chain on a branch, causing fast-forward to fail. Sets up main at S1, branch blue at S4 with 3 intermediate commits, then expires S2 and S3 so only S1 and S4 remain. Asserts fast-forward fails with "not an ancestor". This is existing Iceberg behavior unrelated to max-ref-age-ms.
