Upgrade to TypeScript ~6.0.3 (#19)

* Upgrade to TypeScript ~6.0.3

Adds "types": ["node"] to tsconfig.json — required by TS 6 to resolve
Node globals like path and __dirname. Uses tilde pin since TS doesn't
follow semver.

* Regenerate lockfile with npm 11.14.0

Fixes corrupted peer:true flags on direct dependencies caused by
npm <11.6.3 bug (npm/cli#8690).
