"""
End-to-end style integration tests for the `pkgmgr release` CLI command.

These tests exercise the real top-level entry point (main.py) and mock
the high-level helper used by the CLI wiring
(pkgmgr.cli.commands.release.run_release) to ensure that argument
parsing and dispatch behave as expected, in particular the new `close`
flag.

The tests simulate real CLI calls like:

    pkgmgr release minor --preview --close

by manipulating sys.argv and executing main.py as __main__ via runpy.
