This PR introduces the --inspect-wait flag, which allows debugger to wait for attachement. This flag is useful when you want to debug the code from the beginning. Unlike --inspect-brk, which breaks on the first line, this flag waits for debugger to be connected and then runs the code as soon as a session is established.

It's designed to simplify debugging by removing the need for manual intervention and providing a smoother debugging experience. With support for breaking on the first line and automatic process resumption, it streamlines the debugging process.

Other runtime works include:

I'm not sure I understand the use case? Shouldn't this be solved from the consumer side that can call Debugger.resume (or some such) after attaching with --inspect-brk?

Yes, the --inspect-wait flag acts like a combination of --inspect-brk and the client's Debugger.resume call. It's designed to simplify debugging by removing the need for manual intervention and providing a smoother debugging experience. With support for breaking on the first line and automatic process resumption, I believe it streamlines the debugging process.

Activate inspector on `host:port` and wait for debugger to be attached.
Default `host:port` is `127.0.0.1:9229`.

The docs should likely include additional detail explaining the difference between this and --inspect-brk. Just looking at this I would have no idea as an unfamiliar user which to choose and why.

doc/api/debugger.md Outdated
Using the `--inspect` flag will execute the code immediately before debugger
is connected. This could be problematic if you intend to debug the code from the beginning.
In such cases, you can use the `--inspect-wait` flag instead, which waits for debugger to be attached,
or the `--inspect-brk` flag to break on the first line of the code.

This is good but could be expanded a bit to explain more of the difference. Why would I use one verses the other?

This PR adds a feature so it should be labeled semver-minor PRs that contain new features and should be released in the next minor version. (this is not supposed to be done by releasers).

NiM has had this feature since circa 2020
