/**
 * Recursively walks a directory and returns relative paths of all files
 * matching the given extension.
 *
 * Uses manual recursion instead of `fs.readdirSync({ recursive: true, withFileTypes: true })`
 * to avoid a bug in Node 18.17–18.18 where `withFileTypes` returns incorrect `parentPath` values
 * when combined with `recursive: true`.
 *
 * @param {string} rootDir - The root directory to start walking from.
 * @param {string} extension - The file extension to match (e.g. '.map').
 * @returns {string[]} Relative file paths from rootDir.
