Matt RichardsonandClaude Fable 5.1 0f767ce529 Add a local control socket and nebula ctl (#1975)
Add support for accessing the previously ssh-only debug commands via
`nebula ctl <command>.`

- unix socket (named pipe on windows) for communication
- sockets scoped to the user + an optional group
- in cmd/nebula and cmd/nebula-service, but not nebula.Main
