/**
 * Iterates over an array and returns a promise that resolves with an array of elements
 * that pass the predicate test. Supports concurrency limiting.
 *
 * @template T - The type of the array elements
 * @param array - The array to iterate over
 * @param predicate - The function to test each element (can be async or return a promise)
 * @param concurrency - The maximum number of concurrent operations (default: Infinity)
 * @returns Returns a promise that resolves with an array of elements that passed the test
 *
 * @example
 * const numbers = [1, 2, 3, 4, 5];
 * const evens = await filter(numbers, (n) => n % 2 === 0);
 *
 * @example
 * const users = await filter(userIds, (id) => checkUserActive(id), 2); // Max 2 concurrent checks
