Pull request overview
This PR adds VSCode multi-root workspace configuration to enable running and debugging mongosh tests directly within VSCode using the Mocha Test Explorer extension. The changes refactor test configurations from inline package.json scripts to separate .mocharc.json files for better organization and IDE integration.
- Extracted Mocha test configurations from package.json scripts into dedicated .mocharc.json files across all packages
- Created a multi-root workspace file (mongosh.code-workspace) that includes all packages as separate folders
- Added a dummy test file to support the Mocha Test Explorer functionality

Looks great! I think Copilot's comments are correct, plus one suggestion re: maintaining the workspace config file

Should ./scripts/sort-workspaces also update this file?

This accomplishes my long term dream of being able to debug and run mongosh tests right from inside VSCode.
It does so through a multi-root workspace which you can open by navigating to
mongosh.code-workspaceand clicking open.After installing the recommended https://marketplace.visualstudio.com/items?itemName=hbenl.vscode-mocha-test-adapter you should be able to run tests in UI and debugging!
Some have their quirks i.e.
async-rewriter2needs experimental vm mode etc. but overall I have been using this for a few days and feel much more productive!
