/**
 * Synchronously walks through a directory and its subdirectories, returning an array of file paths.
 *
 * @public
 * @param dir - The directory to start walking from.
 * @param options - Configuration options. See {@link WalkSyncOptions} for details.
 * @returns An array of file paths found during the walk.
 *
 * @example
 * Basic usage:
 * ```typescript
 * const files = walkSync('./path/to/directory');
 * console.log(files);
 * ```
 *
 * @example
 * Ignoring folders:
 * ```typescript
 * const files = walkSync('./path/to/directory', {
 *   ignoreFolders: ['node_modules', 'dist'],
 * });
 * console.log(files);
 * ```
 *
 * @example
 * Filtering by extension:
 * ```typescript
 * const tsFiles = walkSync('./path/to/directory', {
 *   includeExtensions: ['.ts'],
 * });
 * console.log(tsFiles);
 * ```
 *
 * @example
 * Limiting recursion depth:
 * ```typescript
 * const files = walkSync('./path/to/directory', {
 *   depth: 1, // Only files directly in the directory
 * });
 * console.log(files);
 * ```
 *
 * @example
 * Including only specific files:
 * ```typescript
 * const configFiles = walkSync('./path/to/directory', {
 *   onlyFiles: ['package.json', 'tsconfig.json'],
 * });
 * console.log(configFiles);
 * ```
