v3.6.9

This release prepares for the new HookKit Framework API, and fixes a potential crash when using Cydia Substrate as the hooking library.

The upcoming version 3.7.x of Shadow will migrate to using the Modulous Framework for its hooks. This is more of a backend change, but it will pave the way for overall better code quality. Edit: This migration will be in version 4 of Shadow, as the change will require reconfiguration of settings.
