* Added synchronized server-side eye state used by SCP-173 and other observers;

## Keycards, readers, and tools
* Integrated keycards with the custom inventory without maintaining duplicate vanilla mirror stacks;
* Updated shared inventory checks so readers detect custom-only keycards directly;
* Added a screwdriver;
* Added crouch-and-screwdriver reader configuration through both direct interaction and the custom contextual interaction system.
