tests/__init__.py keeps a run offline, its scratch under tmp/ and its
installer cache its own, but only discover -s tests -t . imported it.
discover tests ran with RETROBIOS_OFFLINE unset, scratch on the /tmp
tmpfs and the user's real installer cache, the setting in which e2e
fixtures had written into the shared .cache/large. Every test module now
imports the package first, and a test fails on a module that does not.
test_verify_listing.py took its line with the previous commit.
standalone_probe now holds the host probe lock for one run, its load check included, as core_probe does, and the docs no longer wrap region_check or standalone_probe in flock.
The new probes now refuse abbreviated options, read the GitHub token through github_headers, type every signature and document every option. The site build watches region_check.py and the content list, and validate.yml's tests/** counts as watching the list. The testing guide names the two new test modules.
standalone_probe.py runs the release binary a platform installs (EmuDeck's asset rule for DuckStation and PCSX2), unpacked without running the AppImage runtime, in core_probe's allowlist sandbox with a private Xvfb, strace and core_probe's oracle and record functions. Records go to measurements/<emulator>.jsonl.
