Core: Use named exports in `src/`

The `default` export is treated differently across tooling when transpiled
to CommonJS - tools differ on whether `module.exports` represents the full
module object or just its default export. Switch `src/` modules to named
exports for tooling consistency.

Fixes gh-5262
Closes gh-5292
