Add jco-std NodeJS compat layer for Node24.x & P3

Right now the jco-std node compatibility layer is written against Node 24.X.X (the current LTS, at the latest version), and it would be ideal if we had a version of the compatibility layer that assumed P3 support.

One example of where this is useful is that currently we need to essentially hand back a promise to ensure that P2 components continue running (e.g. after they perform a `server.listen();`) -- this is due to how P3 handles asynchrony, and P3 native shims *should* simply mark the functions being exported as async functions, and StarlingMonkey (well, `componentize-qjs` right now, likely, and `componentize-js` once it's backed by the new `starlingmonkey-ng`) should do the right thing (run the event loop after the function exits) to mimic NodeJS behavior.

Start by locating the jco-std Node compatibility layer and the code paths handling P2 and P3 asynchronous exports. Compare the current Node 24 behavior with the intended P3 behavior, especially around server.listen() and event-loop handling. Done means a P3-compatible layer exists and its async behavior is validated without requiring the current promise workaround.
