## Summary by CodeRabbit
* **New Features**
* Automatic retry for Android certificate installations: failed installs
are retried up to 3 times before marked terminal.
* Installation activities recorded: install/failed-install events (with
details) are logged for better visibility and troubleshooting.
* Resend/reset actions now reset retry state so retries behave
predictably after manual resend.
