feat: add support for synchronous module.registerHooks

Also, add coverage for the debug dump path, and c8 ignore some lines that were being mysteriously uncovered.

I'm not sure why, but tests don't actually run in node 26, due to yargs being interpreted as ESM and loaded improperly from c8.

This will allow us to set up Orchestrion in node versions that deprecate module.register, without spamming stderr with warnings.

Playing with this, it looks like the sync module.registerHooks hooks in node 22 are present, but buggy. I'm going to add a check (in the example code in the docs) to prevent it from being used in that version, rather than only relying on feature detection.

thanks for adding support for registerHooks @isaacs!

I did some research and just force-pushed an update to the docs. (The code is as it was reviewed, no further changes there.) Had to do a bunch of testing to make sure the assumptions were create, but the readme now just specifies a single path forward that works for every situation. I feel like anyone who needs to use strictly --require in old node versions, probably is knowledgeable enough to figure out how to make that work.

Module.register() really was such a messy experiment, hopefully it can rest in peace moving forward 😅
