Fix test infrastructure and paren balance bugs

- Restore balanced org-skill-engineering-standards.lisp from 86eeaab (was broken in HEAD)
- Remove broken org-skill-literate-programming.lisp from asd (paren imbalance since introduction)
- Update run-all-tests.lisp to load files manually (works around ASDF loading issues)
- Test suite now runs: 9/10 pass (1 expected failure due to dirty git tree)

The LP skill gen file has had a paren imbalance since commit 31acf34 - it was never properly tested.
