Fix missing references - issue #200

Root cause 1: SKILL-STRUCTURE-AND-ROUTING.md referenced but doesn't exist
- SkillSystem.md is the canonical skill structure document
- Updated 4 references in CONSTITUTION.md and BrightData/SKILL.md
- Changed SKILL-STRUCTURE-AND-ROUTING.md → SkillSystem.md

Root cause 2: skill-workflow-notification script missing from PAI
- Script exists in Kai (~/.claude/Tools/SkillWorkflowNotification)
- Copied SkillWorkflowNotification to PAI .claude/Tools/
- Updated SKILL.md and SkillSystem.md with correct script path
- Fixed lowercase tools/ → Tools/ (proper Title Case)
- Enhanced workflow routing instructions with dual notification pattern

Files changed:
- .claude/Skills/CORE/CONSTITUTION.md (3 references updated)
- .claude/Skills/BrightData/SKILL.md (1 reference updated)
- .claude/Skills/CORE/SKILL.md (path and instructions updated)
- .claude/Skills/CORE/SkillSystem.md (path and instructions updated)
- .claude/Tools/SkillWorkflowNotification (copied from Kai)

Fixes #200
