The plugin loader execs sibling modules before the package __init__, so a module-level `from . import _read_mem0_json` in _setup.py failed against the empty parent shell and the whole module silently dropped out — every later `hermes memory setup mem0` died with "cannot import name 'post_setup'". The test loads mem0 through the real discovery path from a cold sys.modules and asserts the cached _setup module exposes post_setup (red on base). Also maps the contributor email for #103078 credit.
