/**
 * Transforms an OpenAPI v3 boolean schema object into an internal OAS boolean representation.
 *
 * This function processes OpenAPI boolean schemas by extracting and parsing nullable values,
 * examples, enumerations, and default values. It handles the complete transformation from
 * raw OpenAPI JSON to the SKMTC internal boolean representation with proper validation.
 *
 * The transformation follows a pipeline approach:
 * 1. Parse nullable flag and extract base value
 * 2. Parse example values with nullable support
 * 3. Parse enumeration constraints (typically [true], [false], or [true, false])
 * 4. Parse default values
 * 5. Create final OasBoolean instance
 *
 * @param args - Transformation arguments
 * @param args.value - The OpenAPI v3 boolean schema object to transform
 * @param args.context - Parse context providing utilities and tracing
 * @returns Transformed OAS boolean object with parsed properties
 *
 * @example Basic boolean transformation
 * ```typescript
 * import { toBoolean } from '@skmtc/core';
 *
 * const openApiBoolean = {
 *   type: 'boolean',
 *   default: false
 * };
 *
 * const oasBoolean = toBoolean({
 *   value: openApiBoolean,
 *   context: parseContext
 * });
 *
 * console.log(oasBoolean.default); // false
 * ```
 *
 * @example Boolean with nullable and enum
 * ```typescript
 * const flagBoolean = {
 *   type: 'boolean',
 *   nullable: true,
 *   enum: [true, null],
 *   default: null,
 *   example: true,
 *   title: 'Feature Flag',
 *   description: 'Whether the feature is enabled'
 * };
 *
 * const oasBoolean = toBoolean({
 *   value: flagBoolean,
 *   context: parseContext
 * });
 *
 * console.log(oasBoolean.nullable); // true
 * console.log(oasBoolean.enums); // [true, null]
 * ```
