fix(v0.2.0): resolve macro conflicts, sync load order, and fix skill packaging

- Standardized def-cognitive-tool to 5-argument signature.
- Consolidated *cognitive-tools* as a hash table in package.lisp.
- Removed skills from opencortex.asd to enforce dynamic Skill Engine loading.
- Added missing (in-package :opencortex) to various skill files.
- Fixed let/let* sequential binding issues in emacs-edit and self-edit.
- Updated opencortex.sh to initialize skills before running doctor.
- Fixed uiop:user-homedir-pathname usage in config-manager.
