What an operation does to tmux state.

Carried as data rather than left implicit so a planner, a safety policy,
and a documentation table all read the same answer.

## Members

- `read_only` (attribute): The operation does not change tmux state.
- `destructive` (attribute): The operation removes an object.
- `idempotent` (attribute): Running it twice leaves what running it once leaves.
- `creates` (attribute): The scope of the object it creates, if it creates one.
- `reads_output` (attribute): It captures pane output, so its stdout is the answer.
