Apparently I didn't use my brain cells and rely on the /version
endpoint that Headscale has exposed since 0.26 (our lowest supported
version). Switching to that significantly simplifies the API surface.
Previously REFRESH was only sent once at startup, causing version info
to stay stale. Now the agent refreshes peer data at the cache_ttl
interval (default 3 minutes).
* 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
