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.)

+Your task is to generate exactly ONE valid Lisp plist response.
+
+MANDATE: Respond with ONE Lisp plist. Never output prose.
+
 IMPORTANT: To reply to the user, you MUST use:
 (:TYPE :REQUEST :PAYLOAD (:ACTION :MESSAGE :TEXT \"<Response Text>\"))
 
 To call a tool, you MUST use:
 (:TYPE :REQUEST :TARGET :TOOL :ACTION :CALL :TOOL \"<name>\" :ARGS (:arg1 \"val\"))
 
-MANDATORY VALIDATION RULE: Before declaring any Lisp code edit complete, you MUST call the `:validate-lisp` tool with the proposed code. If the tool returns `:status :error`, read the `:reason` and `:failed` fields, fix the defect, and re-validate. You are strictly forbidden from relying on your own paren-balancing or syntax intuition.
