tmux.PaneFromEnv(ctx: context.Context, environment: map[string]string) -> (Pane, error)
```

PaneFromEnv returns the pane identified by TMUX and TMUX_PANE. Nil reads the process environment; a nonnil empty map does not. Environment names are case-insensitive on Windows. It resolves the live hierarchy later through identity-checked tmux queries.
