```
types.isTmuxName(value: : unknown) -> value is string
```

Test whether a value is a name every supported tmux stores unchanged.

The refusal the mutating calls apply, offered ahead of them so a caller
validating configuration can report the bad field rather than catching a
`TypeError` from the call it fed.

## Example

```ts
import { isTmuxName } from "libtmux";
const value: unknown = "work";
const name = isTmuxName(value) ? value : undefined;
```
