chore: enable composite tsconfig and drop dist references

Marks the root project as composite and pins types: ["node"] so
@types/node resolves cleanly without leaking globals from other ambient
packages. The test tsconfig dropped its outDir (we never emit) and the
back-reference to the root project that composite makes redundant.
Ignores the *.tsbuildinfo artifact composite mode now produces.
