Implement storage-cleaner in node-typescript

Implement the `storage-cleaner` in node-typescript for people who are more familiar with and prefer node-typescript.

Start by locating the node-typescript template and any existing storage-cleaner implementations in the repository. Compare their entry points and behavior, then implement the missing node-typescript version and verify it using the repository's available checks; done means the storage-cleaner is present and functional in that template.
