fix: LISP-STRUCTURAL-CHECK error by separating tests from main lisp files; fix T-as-variable in system-archivist, programming-org, system-memory; fix SOME arg count in org-privacy-tag-p

- Separated test code from programming-lisp.org and programming-org.org into tests/ directory (was tangled to main lisp/, causing LOADER ERROR because export hadn't run yet)
- Added eval-when to load fiveam before test defpackage
- Renamed t→tag in lambda parameters in system-archivist, programming-org
- Renamed t→obj-type in let binding in system-memory
- Fixed missing lambda close paren in org-privacy-tag-p (SOME called with 1 arg)
