/**
 * Adds a prefix and/or suffix to the basename of a given file path or URL.
 *
 * Supports both POSIX-style (`/`) and Windows-style (`\`) path separators,
 * and correctly handles URLs including query strings and hashes.
 *
 * Examples:
 * - "/foo/bar/file.txt" + prefix="pre-", suffix="-post" => "/foo/bar/pre-file-post.txt"
 * - "C:\foo\bar\file.txt" + prefix="pre-", suffix="-post" => "C:/foo/bar/pre-file-post.txt"
 * - "https://example.com/path/file.js?query=1#hash" + suffix="_v2" => "https://example.com/path/file_v2.js?query=1#hash"
 *
 * @param input The input file path or URL string.
 * @param options Optional settings:
 *   - prefix: string to add before the basename (default: "").
 *   - suffix: string to add after the basename but before extension (default: "").
 *   - keepWindowsSeparator: if true, preserves backslashes (`\`) in output (default: false).
 *
 * @returns The modified path or URL string with prefix and/or suffix added to the basename.
 *          Returns the original input if it cannot be parsed or if no prefix/suffix is provided.
