`chel serve`: lots of read permission requests for node modules

[snowteamer]

Problem

When testing chel serve, I'm getting read persmission requests pertaining to the bufferutil and utf-8-validate node modules.

Solution

Do your best to describe what the solution should look like.

If possible, update relevant import statements to reference the correct file extension. This would at least reduce the number of requests to just one per module. Leaving the extension out cause the module lookup algo to try .js, .cjs, .mjs etc in turn until a find is found.
