/**
 * Process `z.boolean()` — renders as a `Checkbox` component (or a component override from the registry).
 * Marks the field as required since boolean fields always have a value (true/false).
 *
 * @param schema - The `$ZodBoolean` schema to process.
 * @param ctx - The walker context providing the form registry for component overrides.
 * @param field - The base FormField to mutate in-place.
 * @param _params - Unused; included for processor signature conformance.
 *
 * @remarks
 * Component can be overridden via `z.registry<FormMeta>()` with `{ component: 'Switch' }`.
 * The `required: true` default reflects that a boolean always resolves to true or false — never undefined.
