 * Parses the `stdout` or `stderr` output of npm, pnpm, modern yarn, or bun to extract structured error information.

 * This parser uses a multi-stage approach. It first attempts to parse the entire `output` as a
 * single JSON object, which is the standard for modern tools like pnpm, yarn, and bun. If JSON
 * parsing fails, it falls back to a line-by-line regex-based approach to handle the plain
 * text output from older versions of npm.
 *
 * Example JSON output (pnpm):
 * ```json
 * {
 *   "code": "E404",
 *   "summary": "Not Found - GET https://registry.npmjs.org/@angular%2fnon-existent - Not found",
 *   "detail": "The requested resource '@angular/non-existent@*' could not be found or you do not have permission to access it."
 * }

 * ```
 * npm error code E404
 * npm error 404 Not Found - GET https://registry.npmjs.org/@angular%2fnon-existent - Not found
 * ```
 *
 * @param output The standard output or standard error of the command.

 * If no HTTP status code is found, it falls back to parsing generic JSON error lines.
