BREAKING CHANGE(core): refactor: reorganize internal module structure to use classes.pp.* modules

- Renamed port proxy and SNI handler source files to classes.pp.portproxy.js and classes.pp.snihandler.js respectively
- Updated import paths in index.ts and test files (e.g. in test.ts and test.router.ts) to reference the new file names
- This refactor improves code organization but breaks direct imports from the old paths
