## Message

```
fix(providers): declare the Pi rollback snapshot capability

CommandPolicy.ensureRollback rejects every rollback command unless
providerRollbackReturnsSnapshot accompanies the rollback capabilities, so
checkpoint reverts on Pi threads failed with 'rollback must return a
providerInstanceId thread snapshot'. rollbackThread already returns the
updated provider thread; declare it.
