feat(v0.2.0): Self-Improvement & Structural Integrity

- Fix critical paren balance issues across harness/skills.org, act.org,
  loop.org, memory.org, and skills/self-edit|emacs-edit.org
- Add :reload-skill cognitive tool for hot-reloading without restart
- Add :generate-embeddings tool and self-edit hot-reload infrastructure
- Wire all new skills (self-edit, emacs-edit, lisp-utils) into main ASDF
- Regenerate all .lisp tangled files via emacs --batch org-babel-tangle
- Add :opencortex/tests ASDF system with 14 test suites
- Fix test files to compile cleanly (self-edit-tests symbol vis, etc.)
