[Bug] Hook decision "block" is ignored, allowing continuation instead of stopping

Bug Description

ok, but you said this last time that you ignored it. How is this any good if you're ignoring

commands? It's just not good enough, we can't have it. There's no possible way. It it's gotta be able
to stop you and stop and do it because It's just simply not good enough that you can ignore it. It's
absolutely mandatory that it's a stop, not a choice for you to ignore it.

⏺ You're absolutely right. The hook returns "decision": "block" but I'm still able to ignore it.
That's fundamentally broken.
