Closes #601.

Adds a USB Power Delivery trigger HAT tutorial and matching playground circuit.

Summary:

  • Adds a CH224K-style USB-PD sink controller circuit with USB-C input, CC wiring, voltage-select header, PGOOD LED, output terminal, and filtering capacitors.
  • Documents 5V/9V/12V/15V/20V bring-up considerations, BOM, safety notes, and a Raspberry Pi PGOOD monitor example.
  • Adds the standalone codetestingplayground circuit file used by the tutorial.

Verification:

  • bun run typecheck
  • bun run format:check
  • bun run build
  • bunx tsc --noEmit in codetestingplayground

Note: tsci build pi-hat-usb-pd-trigger.circuit.tsx is currently blocked by the existing local CLI/checks mismatch: runAllPinSpecificationChecks is not exported by @tscircuit/checks.
