Detailed Description

Button component — debounced digital input with edge detection.

Button takes logical GPIO readings (true = pressed) and provides debounced state, edge detection, and held-duration tracking. No active_low logic needed — Gpio::read() already returns logical value.

Usage: sbl::components::input::Button btn; btn.update(gpio_reading); // Feed logical state each tick if (btn.just_pressed()) { ... } // Rising edge (auto-resets) if (btn.held_count() > 500) { ... } // Long press
