Hungerdream b9a3ddd9e3 feat(ansible): add mysql-rollback playbook for instance cleanup ...

Add a compensating playbook that removes a single delivered MySQL
instance from a target host. The rollback scope is pinned by
target_hosts + instance_name + data_disk, with pre-task assertions
rejecting instance names or disk paths outside the delivery layout
to prevent accidental deletion.

- stop and disable mysql-delivery@<instance>.service, reset failed state
- remove instance data dir, install dir, config file and run dir
