fix: prepare wxt before typecheck in browseros-agent

The typecheck and compile scripts failed on fresh checkouts with
TS5083 because tsconfig.json extends .wxt/tsconfig.json, which is
gitignored and only generated by 'wxt prepare'. Run wxt prepare
before tsgo so the extended config and wxt.d.ts are always in place.
