wip: paren balance fixes in policy blocks + engineering standards scaffolding

- Fix unbalanced parens in org-skill-policy.org (8 blocks)
- Add org-skill-engineering-standards.lisp scaffolding
- Add org-skill-self-fix.lisp helper
- Add test runners and tool-permissions tests

Note: Some fixes may be over-corrections. Full structural audit needed.
