+   *
+   * This function operates in three main steps:
+   * 1. Pruning snapshots from root/non-versioned folders.
+   * 2. Pruning snapshots from versioned folders.
+   * 3. Removing orphaned snapshots that do not belong to any existing folder or folder version.
+   *
+   * The function processes snapshots in batches, determined by the `PRUNE_FOLDER_BATCH_SIZE` constant,
+   * to manage the large datasets without overwhelming the DB.
+   *
+   * Steps:
+   * - Fetch a batch of folder IDs.
+   * - For each batch, use a Common Table Expression (CTE) to rank snapshots within each folder by their creation date.
+   * - Identify and delete snapshots that exceed the project's point-in-time version limit (`pitVersionLimit`).
+   * - Repeat the process for versioned folders.
+   * - Finally, delete orphaned snapshots that do not have an associated folder.
