feat(core): Skills consolidation and v0.2.0 TUI integration

- NEW: org-skill-utils-lisp (consolidated from org-skill-lisp-utils)
  * 3-phase validation: structural, syntactic, semantic
  * Sandboxed eval, AST extraction/injection/wrapping
  * Format, list-definitions utilities

- NEW: org-skill-utils-org (consolidated from org-skill-emacs-edit)
  * Read/update/delete org headlines
  * Property management, TODO state handling
  * ID-link and internal link support

- DELETE: org-skill-lisp-utils (merged into utils-lisp)
- DELETE: org-skill-emacs-edit (merged into utils-org)
- RENAME: run-all-tests.lisp -> run-tests.lisp

- HARDEN: Skill loader with improved lisp keyword handling
- FIX: Package jailing issues with def-cognitive-tool macro conflicts
- ADD: Setup wizard (opencortex setup) and doctor (opencortex doctor)
- ADD: TUI client with Croatoan for native terminal rendering

- REMOVE: Dynamic loading from opencortex.asd (use :force t instead)
- CLEANUP: Test file consolidation (removed duplicate test suites)
