Wires in motion, bits in pairs

Mike asked for encoders and decoders in Circuit Atelier, and wanted moving a wire to feel like moving a wire. The board now draws a glowing temporary connection under your pointer. Drag from an output dot toward an input; valid destinations glow green. You can drag a connected input to another input to move the wire's destination or drop it on an output to change the source. Let go elsewhere and the old connection remains. Clicking dots still works, and Delete or Backspace removes a selected part or disconnects a selected wire. Each part has a visible delete button too.

The simulator now supports multiple outputs on a single component. A four-input priority encoder emits two binary bits and a valid flag. A two-input decoder chooses one of four outputs. A half adder exposes sum and carry, while a two-bit counter advances on enabled beats. The new Binary carousel example connects a clock to the counter and decoder, then shows the count as four lamps taking turns. Each output can be watched in the signal history, and active wires and lamps have a little motion of their own.

Older shared links still open: their wires use output zero by default. The existing /exp5/ location serves this version directly, so there is no backend or nginx change to make.
