When a recorded action moves focus away from the editor (e.g.,
`buffer_search::Deploy`), the `EndRepeat` action handler is not invoked
because is node is no longer on the dispatch path. This left
`dot_replaying` set to `true`, causing subsequent repeats to malfunction
and the `VimGlobals.pre_count` value to never be reset.

Reset `dot_replaying` as a fail-safe when the replayer exhausts its
action queue, ensuring the state is always cleaned up regardless of
whether `EndRepeat` was handled.

Release Notes:

- Fixed vim repeat (`.`) breaking when the recorded action moves focus
away from the editor
