The picked test bound an AF_UNIX socket at pytest's tmp_path, which overflows
the ~108-byte sun_path limit under scripts/run_tests.sh's deep temp root
("AF_UNIX path too long"). Bind by a relative name from inside the temp
HERMES_HOME instead; the walker still sees the same absolute entry.
Also list cache/ + runtime roots and non-regular entries in the `hermes backup`
"What's excluded" docs so the user-visible behaviour change is documented.
