Subject: [PATCH] ci: type-check the web target on pushes to main and on pull
 requests

The web bundle is only built when a release is published, so a desktop-only
call in shared code can reach main unnoticed and fail the next release at
the wasm step (#1224, #1347). Run cargo check for wasm32-unknown-unknown on
the app and the web worker instead.
