feat: module interaction system with wiring panel

Add a new "module" interaction type where doors/devices define ports
(in/out) and a JS verify function. Players wire their gadget's I/O
to the module's ports via a canvas-rendered wiring panel, then execute
to verify the circuit logic.

- New wiringPanel.js: full wiring UI with keyboard nav, bezier wires,
  mini circuit evaluator, and verify execution
- AND-gate example door in Circuit Lab (tile 9,1)
- Editor support: module type with ports editor and JS verify textarea
- Integrated into gameMode, worldInput, worldRenderer
