* Added backoff and liveness probes for better management
* Switched IPC to a simple text based system
* Lookups don't directly touch the agent now
* Use the database as a source of truth
we also have added the necessary logic to auto prune ephemeral nodes because
headscale doesn't seem to automatically remove them. this change made use of a database
which is now stored in the persistent headplane directory.
