The entire process is as follows: 1. Drop the tablet. 2. Successfully clone the tablet in full. 3. Start the incremental clone. 4. Start to move the tablet to the trash (the process of actually cleaning the data begins from step 1, where the tablet was dropped). 5. The incremental clone fails. 6. The incremental clone is successfully retried. Step 4 moved the data that was just pulled from the full clone to the trash, leading to data loss. The failure in step 5 of the incremental clone was also due to the deletion of the just-pulled snapshot data. Fix： When cloning, check the tablet status and determine if the tablet directory has already been moved to the trash directory. If it has not been moved to the trash, the clone thread should help move it to the trash directory.

Issue Number: close #xxx
The entire process is as follows:
Step 4 moved the data that was just pulled from the full clone to the trash, leading to data loss.
The failure in step 5 of the incremental clone was also due to the deletion of the just-pulled snapshot data.
Fix：
When cloning, check the tablet status and determine if the tablet directory has already been moved to the trash directory. If it has not been moved to the trash, the clone thread should help move it to the trash directory.
