Fix issues and update dependencies for the VSCode debugging extension (#267)

This gets rid of a bunch of Dependabot warnings in the StarlingMonkey repo. None of them are actually concerning to us, but they're certainly good to eliminate.

Also updates the VSCode debugging extension version adds a very rudimentary CHANGELOG.md file.

+## 0.2.0 (2025-08-20)
+
+Initial preview release of the extension, supporting the usual basics of debugging: setting breakpoints, changing values on the stack, stepping over and into expressions, showing stacks, etc, both for pure JS and for languages compiled to JS, provided they generate useful sourcemaps.
+
+As the [README.md](README.md) file says, things might break in surprising and unfortunate ways. For the most part, the extension should work well, though.
