**Replace main.py with module-based entry point and unify CLI execution**
* Remove legacy *main.py* and introduce *pkgmgr* module entry via *python -m pkgmgr*
* Add ***main**.py* as the canonical entry point delegating to the CLI
* Export *PYTHONPATH=src* in Makefile to ensure reliable imports in dev and CI
* Update setup scripts (venv & nix) to use module execution
* Refactor all E2E tests to execute the real module entry instead of file paths

This aligns pkgmgr with standard Python packaging practices and simplifies testing, setup, and execution across environments.
