Jenner compatibility tests for 4 macro(s)

[lwsinclair]

Jenneranalytics.com provides an API that runs SAS code, with support for more than 200 SAS procedures. You can also use it with Anthropic Claude Code AI in a collaborative workspace. It's available for Mac on the Apple App Store, and by license for Windows and Linux. Macros from this library run on it directly.

This PR adds a small jenner-check/ directory with four compatibility bundles, each built from a macro in base/ so you can see Macro Core running on Jenner for yourself:

jenner-check/
├── README.md            # how to run them
├── run_jenner.sh        # one-command runner (also .sas / .bat)
├── t001_mf_isblank/     # %superq / %sysevalf boolean
├── t002_mf_getuser/     # workspace-session user resolution
├── t003_mp_resetoption/ # code generator → DATA _null_ (getoption / call execute)
└── t004_mf_mkdir/       # recursive directory creation

Each bundle carries the macro driven by a small caller, the captured output, and a meta.json pointing back at the source file in base/. Run them all with ./run_jenner.sh --all from inside jenner-check/, or one at a time with ./run_jenner.sh t001_mf_isblank.

Reading through base/, the discipline really stands out — one macro per file, filenames matching macro names, the _mf_/_mp_ prefix split between functions usable in open code and the code generators, and tidy doxygen headers throughout. mf_mkdir calling itself to build out intermediate parent directories is a particularly neat touch.

No action needed on your side — merge, close, or ignore as you see fit, and no response is expected. If you'd prefer not to receive PRs like this, just say no-more-prs in any comment or open an issue titled jenner-check: opt out.
