Whether running a request twice leaves tmux as running it once does.

Decided from the commands themselves: a request is idempotent only when every command in it
reads and changes nothing. Anything this library cannot tell is a read counts as a change, so a
failure never reports a mutation as safe to resend.

## Members

### Other members

- `IDEMPOTENT` (constant): Every command only reads; sending it again cannot change tmux.
- `NOT_IDEMPOTENT` (constant): At least one command may change tmux, so a second send may apply it twice.
- `of` (method): The idempotence of a request made of {@code commands}, each an argv.
