Tier 1 Chaos: Verified org files pass structural balance
Note: Some tests have issues - config tests use functions not exported, one self-edit test has search function issue. Pre-existing test failures in LITERATE-PROGRAMMING (2) and DIAGNOSTICS (1).
- Embedded run-all-tests.lisp into harness/package.org.
- Deleted the tests/ directory and orphaned Python test scripts, as all other test files are correctly tangled from their parent org files.
