Improve VectorTests page and import path

jonfroehlich · jonfroehlich · commit ade13447bd5c · 2026-05-20T09:53:36.000-07:00
Add HTML metadata and user instructions (lang, charset, heading, and note to open the dev console) and remove the #test-results div for a clearer test page. In sketch.js add a doc comment describing the Vector unit tests and update the makelab.math import to a relative path ('../../../../dist/makelab.math.js') to match project layout.
