Reinstall everything from a clean node_modules and package-lock.json
state.
Re-generate list of bundleDependencies and node_modules/.gitignore with
a script that does the right thing based on actual dependency state.
Also some hand-crafted deduping of various deps that got nested as a
result.
Really excited to start self-installing again soon. @npmcli/arborist is
a whole lot smarter about pruning unnecessary duplicate modules in the
normal course of installation.
