import assert from 'node:assert';
/**
 * Lightweight assertion helper that provides a fluent API for value checks.
 *
 * Returns an object with `toBe` and `toBeInstanceOf` methods for asserting
 * equality and type, respectively. Intended for internal CLI validation logic.
 *
 * @template T - The type of the value being asserted.
 * @param value - The value to assert against.
 * @returns An object with `toBe` and `toBeInstanceOf` assertion methods.
 *
 * @example
 * ```ts
 * expect(status).toBe(200, 'expected HTTP 200');
 * expect(result).toBeInstanceOf('object', 'expected an object');
 * ```
