Detailed Description

C++ board-level helper for the C7222 Pico W board.

This class provides a small, beginner-friendly API for accessing the board's LEDs and buttons through the higher-level Led and Button types. It hides GPIO pin numbers behind enums and ensures a consistent, simple access pattern across platforms.

Design intent:

• Board-centric API: Use logical IDs (LedId, ButtonId) instead of raw GPIO numbers.
• Simple lifecycle: Construction performs initialization; then retrieve references to LEDs/buttons using GetLed()/GetButton().
• No accidental copies: Inherits from NonCopyableNonMovable to avoid copying the board abstraction.

Mapping assumptions (C7222 Pico W board):

• LEDs are active-low and mapped to GPIOs 16–21.
• Buttons are mapped to GPIOs 2–5 (active-low with pull-ups by convention).
