build: typescript ^7.0.2 (native compiler)

TypeScript 7 is the native Go compiler; the npm package is a thin shim
that resolves a platform-specific native binary.

Safe here because the build does not emit through tsc — the bundler does,
so tsc is typecheck-only and the built artifact is unaffected. Gated on a
measured comparison of both compilers against this same config: TS7
introduces no errors TS 5.9 did not already report.

typescript now ^7.0.2
