tmux.NewServerFromEnv(environment: map[string]string) -> (Server, error)
```

NewServerFromEnv returns a server configured from TMUX without starting tmux. It snapshots the process environment once. A nonnil environment supplies discovery values and overrides that snapshot for later tmux processes; an empty map therefore has no TMUX discovery value. Names follow the platform's environment rules and are case-insensitive on Windows.
