Make comlink available for chrome extensions

chrome extensions have background javascript and popup javascript they both communicate with each other via postMessage. comlink can provide a great help there to eliminate all message passing nuances. Please add the support of comlink to chrome extensions

Start by examining how Comlink currently handles communication and how Chrome extensions connect background and popup JavaScript through postMessage. The issue does not name files, tests, or an entry point, so first clarify the intended extension support and its expected API before implementation. Done should mean documented, tested support for this communication pattern.
