use explicit path when importing

[jimmywarting]

A file extension must be provided when using the import keyword to resolve relative or absolute specifiers. Directory indexes (e.g. './startup/index.js') must also be fully specified.

This behavior matches how import behaves in browser environments, assuming a typically configured server.

this guessing game of what to import using remote path resolver is impossible b/c external resources can't play guessing games cuz it dose not have direct access to the files on the hard drive and needs to be resolved via http
