* feat: Add regression test for issue #2571
This commit adds a regression test for issue #2571. The issue describes a scenario where `gopass sync` incorrectly removes public keys for sub-stores under certain conditions.
The new integration test in `tests/sync_test.go` reproduces the steps outlined in the GitHub issue to ensure that the public key is not deleted after running `gopass sync`.
* [fix] Fix lint errors
