Reorganize: skills/ directory + move memory to docs/

skill-legal-decision/ → skills/decision/
skill-legal-assistant/ → skills/assistant/
skill-legal-docx/ → skills/docx/
memory/*.md → docs/

Also removed: TASKS.md (use TaskMaster), classifier.py (replaced by local_classifier.py)
Updated all references in CLAUDE.md, scripts, PRDs, docs.
