* 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. https://chatgpt.com/share/693c9056-716c-800f-b583-fc9245eab2b4

E2E integration tests for the `pkgmgr mirror` command family.

This test class covers:
|
|
|
|
- pkgmgr mirror --help
|
|
- pkgmgr mirror list --preview --all
|
|
- pkgmgr mirror diff --preview --all
|
|
- pkgmgr mirror merge config file --preview --all
|
|
- pkgmgr mirror setup --preview --all

|
|
|
All of these subcommands are fully wired at CLI level and do not
|
|
require mocks. With --preview, merge and setup do not perform
|
|
destructive actions, making them safe for CI execution.
