This causes the copilot LSP to exit immediately on start with no error or LspLog info. It is going to require some debugging to merge.

I debugged this as I'm quite interested in #365, and I suspect that this update is a prerequisite (although I'm not sure).

The reason this is now failing is that the new language-server.js seems to have this near the bottom:

require.main === module && (pet(), s3e(get)).main();

This means it is expecting to be run directly from Node instead of how we do it indirectly through index.js. Is there a reason we go through a level of indirection?
