/**
 * Batch removal record of the Lance index job retention GC: one journal entry
 * carries every resolved job id removed in one clean round. A plain id list
 * suffices (no watermark): the journal is ordered, so every upsert of a removed
 * job precedes this record, and no later stale record can resurrect it.
 * Serialization is the standard Gson stream, see {@link LanceIndexJob}.
