What addons changed

Besides adding modules, an addon can change how parts of Myriad work: how rotations turn, where blocks are placed, when inventory clicks go out, how highlights look. Some replace a whole part (an addon might bring its own rotations), some only for their own modules, some only on one server.

The Hooks window (from the launcher) shows all of it:

• Services: the parts an addon took over, and which is in use for everyone right now.
• Hooks: single decisions addons make instead of Myriad, and when (for a module, a server).

Each is a card. Click one to turn it off; click again to turn it back on. If one of them ever breaks (throws an error), Myriad turns it off by itself until you restart, and the card says failed.

From chat: .hooks lists them, .hooks off <name> / .hooks on <name> switch one, and .hooks why <module> says which of them affect a module.
