Updated tests to use compiled cjs output instead of TS source

- Tests now import from `cjs/` instead of `src/` because Node.js cannot
directly require TypeScript files. The build process compiles `.ts`
source files to CommonJS `.js` files in `cjs/`, which is what tests need to execute.

- The `pretest` script ensures `cjs/` is built before tests run, so
tests always run against the latest compiled output.
