/**
 * `@UseGuard()` decorator to apply one or more guards to methods.
 * Guards are used to handle permission checks before executing a method.
 * Each guard must use `@Guard` decorator and implement the `canActivate` method, which determines
 * whether the method should be allowed to execute based on the provided interaction and arguments.
 * This decorator ensures that all guards pass validation before calling the original method.
 * Supports guards that are parameterized (accepting additional parameters).
 *
 * @param guards - One or more guard classes to apply. These can be regular guards or guards with additional parameters.
 *                 - If providing a guard with parameters, it should be an object with:
 *                   - `provide`: The guard class to instantiate. Must implement `GuardInterface`.
 *                   - `params`: A record of key-value pairs to be passed as additional properties to the guard instance.
 * @returns A method decorator function that applies the guards to the method.
 *
 * @example
 * ```typescript
 * @Command('profile-{id}', CommandType.BUTTON)
 * @UseGuard(
 *   { provide: RateLimiterGuard, params: { limit: 2, window: 3000 } },
 *   ButtonInteractionGuard
 * )
 * async showProfileById(interaction: ButtonInteraction, { id }: { id: string }) {
