Sebastian Mark ab2e8c161d feat: implement stale client removal after timeout
- add goroutine to remove stale clients from the connection pool
- update client struct to track `LastPong` time
- set write deadline for websocket connections
- move package variables and const to `vars.go`
- log additional information when broadcasting errors
