Adds the ESP32-C3 SuperMini (18 x 22.5mm) as a reusable board: two rows of eight 2.54mm-pitch header pins carrying 5V/GND/3V3 and GPIO0-GPIO10, GPIO20 and GPIO21, with PCB, schematic and 3d snapshots. The pinout and the board's mechanical constants live in pinout.ts, so the footprint's pin positions and the chip's pinLabels/schPinArrangement are all derived from one list instead of repeating it. The outline is quantized to 1e-6mm before it is handed to the board: the corner arcs go through Math.cos/sin, which are not required to be correctly rounded and differ by ~1 ULP between libm implementations, which would otherwise make the PCB snapshot render differently per platform.

<Esp32C3SuperMini />board — two rows of eight 2.54mm-pitch header pins carrying 5V/GND/3V3 and GPIO0-GPIO10, GPIO20 and GPIO21. Exported from index with PCB, schematic and 3d snapshots.The outline is quantized to 1e-6mm before it is handed to the board. The corner arcs go through
Math.cos/Math.sin, which are not required to be correctly rounded and differ by ~1 ULP between libm implementations, so without this the PCB snapshot renders a few digits differently per platform.
