Add a comprehensive tutorial for building an ESP32-WROOM-32 minimum system circuit with power supply (USB-C + AMS1117-3.3 LDO), decoupling capacitors, reset/boot mode circuits, and status LED. Closes tscircuit/docs-old#47 /claim tscircuit#47
Create a tutorial for drawing letters with LEDs on a PCB using the @tscircuit/alphabet library. Includes a reusable LedLetter component that supports A-Z, automatic LED placement along letter strokes, current-limiting resistors, and multi-letter display examples. Addresses tscircuit/docs-old#50 /claim tscircuit#50
