Avoid invalid disconnection notifications in case the closed race dials.
In this PR resolve multiple race condition questions. Easier to understand the fix based on commit by commit.
- Remove store dependency from notifier
- Enforce the notification orders
- Fix invalid disconnection notification
- Ensure the order of the events on the consumer side
Fix nil pointer in Relay conn address
Meanwhile, we create a relayed net.Conn struct instance, it is possible to set the relayedURL to nil.
panic: value method github.com/netbirdio/netbird/relay/client.RelayAddr.String called using nil *RelayAddr pointer
Fix relayed URL variable protection
Protect the channel closing
- Clients now subscribe to peer status changes.
- The server manages and maintains these subscriptions.
- Replaced raw string peer IDs with a custom peer ID type for better type safety and clarity.
The nhooyr.io/websocket package was renamed to github.com/coder/websocket when
the project was transferred to "coder" as the new maintainer.
Use the new import path and update go.mod and go.sum accordingly.

Fixes an issue on macOS where the server throws errors with default settings:
failed to write transport message to: DATAGRAM frame too large.
Further investigation is required to optimize MTU-related values.
When the remote peer switches the Relay instance then must to close the proxy connection to the old instance.
It can cause issues when the remote peer switch connects to the Relay instance multiple times and then reconnects to an instance it had previously connected to.
* Move the handshake logic to separated struct
- The server will response to the client after it ready to process the peer
- Preload the response messages
* Fix deprecated lint issue
* Fix error handling
* [relay-server] Relay measure auth time (#2675)
Measure the Relay client's authentication time
Fix leaked server connections
close unused connections in the client lib
close deprecated connection in the server lib
The Server Picker is reusable in the guard if we want in the future. So we can support the server address changes.

This update adds new relay integration for NetBird clients. The new relay is based on web sockets and listens on a single port.
- Adds new relay implementation with websocket with single port relaying mechanism
- refactor peer connection logic, allowing upgrade and downgrade from/to P2P connection
- peer connections are faster since it connects first to relay and then upgrades to P2P
- maintains compatibility with old clients by not using the new relay
- updates infrastructure scripts with new relay service
