Return	Type	Effect
Allow/deny close	{ allow?: boolean; reason?: string } or Promise<{ allow?: boolean; reason?: string }>	If allow === false, close execution is blocked.
No return value	void or Promise<void>	Close execution continues.

When the gate blocks (allow === false), the runtime returns CLOSE_BLOCKED_BY_HOOK:${reason} or CLOSE_BLOCKED_BY_HOOK.
