One tmux invocation: the operations it carries, in order.

## Members

- `indices` (method): The plan indices this invocation runs, in order.
- `is_marked` (method): Whether this invocation addresses a new pane through tmux's `{marked}` register, which is what lets a create share an invocation with the operations that decorate it.
- `len` (method): How many operations share this invocation.
- `is_empty` (method): Whether this invocation carries no operations, which a planner never produces.
- `reason` (method): Why this invocation is separate from the one before it.
