feat: Add stacker_loop option

This commit introduces a new configuration option `stacker_loop` to
control the behavior of the `stack_with_left` function.

When `stacker_loop` is set to `false` in the user's `config.conf`,
invoking `stack_with_left` on the first window in the layout will have
no effect.

When `stacker_loop` is set to `true` or is not present in the config
file, the default behavior is maintained, where `stack_with_left` on the
first window will wrap around and create a stack with the last window.

This provides users with more control over the stacking behavior in the
stacker layout.
