fix: make PYTHONPATH test assertion repo-name agnostic (#44)

* fix: make PYTHONPATH test assertion repo-name agnostic

The test was asserting that PYTHONPATH contains "archaeology" or
"DEV-ARCH" — hardcoded local directory names. In CI the repo is cloned
as "devarch-framework", so neither substring matched.

Replace with an assertion that PYTHONPATH is an absolute path (which is
the actual invariant the CLI code guarantees via Path(__file__).parent.parent).

Fixes #39

* fix: use os.pathsep in PYTHONPATH test assertion
