Typecheck on the native compiler, keep 6 for the tools

typescript 7.0.2 is the native compiler and exports no JavaScript API, and
next below 16.3 wants typescript/lib/typescript.js, which the native compiler
does not ship: the check fails and next shells out to `pnpm add typescript`
mid-build, which a frozen lockfile or an offline runner turns into a failed
build. So 7.0.2 comes in aliased as tsgo and does the typechecking, and
typescript stays on the 6 line for next. The docs site: 10 diagnostics before and after.
