refactor: move act under internal
The runner is an application, not a library. `act/model` and `act/exprparser` were the last packages anything outside this repository consumed and they now live in actionslib, so nothing needs the rest of `act` to be importable, and keeping it importable invites the coupling that was just removed. Import paths only, the files are unchanged. Assisted-by: Codet:GPT-5.1-Codex
