tmux.GlobalSessionScope.RunHook(ctx: context.Context, name: string) -> error
```

RunHook asks tmux to run one global hook directly. It intentionally performs no racy target preflight; stale targets and global execution context remain tmux-defined. Completed failures are secret-safe option errors; cancellation does not prove hook delivery or execution did not occur.
