feat(governance): wave 4 enforcement - 41% improvement (56% → 79%)

Implements 9 additional enforcement mechanisms across all priority levels:

🔒 HIGH PRIORITY - Architectural Enforcement:
✅ API Security Validator (inst_013/045) - scripts/check-api-security.js
   - Scans API endpoints for rate limiting
   - Validates authentication requirements
   - Detects sensitive runtime data exposure

✅ GitHub Repo Structure (inst_063_CONSOLIDATED) - scripts/check-github-repo-structure.js
   - Validates repository structure requirements
   - Ensures tractatus-framework remains implementation-focused

⚙️ MEDIUM PRIORITY - Process/Workflow:
✅ Human Approval Tracker (inst_005) - scripts/track-human-approvals.js
   - Logs approval requirements for major decisions
   - Tracks pending approvals

✅ Context Pressure Comprehensive (inst_019) - scripts/verify-context-pressure-comprehensive.js
   - Verifies all pressure factors included
   - Validates comprehensive context accounting

📋 LOW PRIORITY - Behavioral/Values:
✅ Behavioral Compliance Reminders (inst_047/049) - .claude/hooks/behavioral-compliance-reminder.js
   - Reminds never to dismiss user requests
   - Prompts to test user hypotheses first
   - Integrated into UserPromptSubmit hooks

✅ Dark Patterns Detector (inst_079) - scripts/check-dark-patterns.js
   - Scans UI code for manipulative patterns
   - Detects confirm shaming, hidden checkboxes, timed popups

📊 Enforcement Progress:
- Wave 1: 11/39 (28%)
- Wave 2: 18/39 (46%)
- Wave 3: 22/39 (56%)
- Wave 4: 31/39 (79%)
- Total improvement: +20 instructions = +178% from baseline
- Remaining gaps: 8/39 (21%)

🎯 Remaining 8 Gaps (requires runtime/process enforcement):
- inst_039: Document processing verification
- inst_043: Web form input validation (runtime)
- inst_052: Scope adjustment authority tracking
- inst_058: JSON/DB schema sync validation
- inst_061: Hook approval pattern tracking
- inst_072: Defense-in-depth credential layers
- inst_080: Open source commitment (policy)
- inst_081: Pluralism principle (foundational value)

🔄 Enhanced Hooks:
- UserPromptSubmit now runs 3 hooks (triggers, all-commands, behavioral)
- Added behavioral compliance reminders for session guidance
