chore(cli): type currentAction as CliAction

[kaizencc]

CliAction type feels slightly off as it should be CliAction and not ToolkitAction. This makes the default make sense. Either way, the internal property of CliIoHost is typed to CliAction.

In practice this probably doesn't matter because I don't think we are initializing CliIoHost with anything but none.
