Original Pull Request: https://github.com/netbirdio/netbird/pull/5926

State: closed
Merged: Yes

Describe your changes

Run macOS sleep/wake detection from the daemon instead of the UI so it keeps working when the UI isn't running (headless installs, UI quit/crashed). Also replaces the CGO implementation with purego.

Move sleep detection from client/ui into the daemon; drop the NotifyOSLifecycle gRPC and regenerate proto
Rewrite client/internal/sleep/detector_darwin.go using purego (IOKit + CoreFoundation via dlopen), with a single process-lifetime callback thunk and a dedicated OS-locked goroutine for the CFRunLoop
Make Register synchronous: surface IOKit registration failures to the caller, and have Deregister await runloop setup so teardown can't skip cleanup on a fast register/deregister
Add NB_DISABLE_SLEEP_DETECTOR env var to opt out of sleep detection
Promote ebitengine/purego to a direct dependency

Summary by CodeRabbit

New Features
- Server now starts OS sleep/wake detection automatically; UI no longer initializes it and events are forwarded internally.
Refactor
- Sleep detection rewritten to use runtime dynamic bindings, serialized lifecycle transitions, safer callback dispatch, and robust startup/shutdown.
Chores
- Made native runtime binding dependency explicit in module configuration.
Breaking Change
- Removed legacy OS-lifecycle RPC — external lifecycle notifications must stop.
Config
- Detector can be disabled via NB_DISABLE_SLEEP_DETECTOR.
