 * Given a MongoClientOptions, this function resolves the set of runtime options, providing Nodejs
 * implementations if not provided in `options`, and returns a `Runtime`.
 *
 * Resolution is asynchronous because the default `os` adapter is loaded via a dynamic `import()`.
 * Unlike `require`, dynamic import exists in every module system the driver ships into or is
 * bundled into (CJS, ESM, and bundled ESM output), and the literal specifier keeps it
 * statically analyzable for bundlers. The promise is created during synchronous
 * options parsing and awaited later by consumers, so the public constructor stays synchronous.
