* chore(pd): make esbuild find `js-yaml` correctly

For some reason, esbuild uses the upstream version of `js-yaml` rather
than the @zkochan fork. This throws a little plugin into esbuild's
resolution to resolve `js-yaml` using Node's resolvers instead, which
seems to find the correct version.

There may be a better way to do this, especially considering esbuild
does fine in the normal build of pnpm as far as I can tell... though
that may be because `tsc` does the first pass.

ref #7583

close #7603

This change makes it so that `pd` starts a Node process and passes
`--enable-source-maps` to it, which allows for better debugging when
`pd` commands fail.

I'm not sure if this will work on Windows since it changes a simple
`require` to a `childProcess.execSync`.

* fix(get-context): avoid excess purge prompts

pnpm sometimes needs to purge modules folders (node_modules) when
certain configuration changes (in other words, when it needs to start
from scratch).

This prompt, problematically, was getting triggered asynchronously for
each importer in the workspace that needed a purge, which would
sometimes lead to gargantuan prompts instead of one consolidated prompt.

The fix is to queue up which importers need a purge, then fire the
prompter all at once.

Closes #7320

* fix: reuse ImporterToPurge type

* refactor: apply suggestions from code review
