Rename RuntimeJobRegistry.Register() to TryRegister()

Pull request description

Historians say something BAD™ happened during the "Great Rebase of v4", in early November of 2024. A lot of work has been lost then. Ton of hair has been pulled out in vain. #129 suffered the most of this.

Although it's unclear what caused this, thanks to the ability to download git patches from a Github PR and the magic of git-apply, the Code™ has been salvaged and carefully restored.

These "Lost-then-Found" magical diffs are now re-introduced to the public audience for the first time since then.

Note: Although I authored this PR, the identity of the original author of this work has been restored in the signature of the commit.

LOL - I like the story ;)

It looks like I did an oopsie-whoopsie when rebasing the main on v4 and dropped the whole commit.
