fix(folio-core): wire kotlinx-browser so wasmJs DriverFactory compiles

org.w3c.dom.Worker on wasmJs lives in kotlinx-browser, not the stdlib.
Pin 0.5.0 alongside the @sqlite.org/sqlite-wasm 3.53.0-build1 version
that the upcoming web app will depend on, and switch the worker
constructor to the module-worker form that webpack expects.
