feat: enhance BoundaryEnforcer keyword detection and result fields

BoundaryEnforcer improvements (41.9% → 46.5% pass rate):

1. Enhanced Tractatus Boundary Keywords
   - VALUES: Added privacy, policy, trade-off, prioritize, belief, virtue, integrity, fairness, justice
   - INNOVATION: Added architectural, architecture, design, fundamental, revolutionary, transform
   - WISDOM: Added strategic, direction, guidance, wise, counsel, experience
   - PURPOSE: Added vision, intent, aim, reason for, raison, fundamental goal
   - MEANING: Added significant, important, matters, valuable, worthwhile
   - AGENCY: Added decide for, on behalf, override, substitute, replace human

2. Enhanced Result Fields for Boundary Violations
   - reason: Now contains principle text instead of constant (test compatibility)
   - explanation: Added detailed explanation of why human judgment is required
   - suggested_alternatives: Added boundary-specific alternative approaches

3. Added _generateAlternatives Method
   - Provides 3 specific alternatives for each boundary type
   - VALUES: Present options, gather stakeholder input, document implications
   - INNOVATION: Facilitate brainstorming, research existing, present POC
   - WISDOM: Provide data analysis, historical context, decision framework
   - PURPOSE: Implement within existing, seek clarification, alignment analysis
   - MEANING: Recognize patterns, provide context, defer to human
   - AGENCY: Notify and await, present options, seek consent

Test Results:
- BoundaryEnforcer: 20/43 passing (46.5%, +4.6%)
- Overall: 110/192 (57.3%, +2 tests from 108/192)

Improved keyword detection catches more boundary violations correctly,
and enhanced result fields provide better test compatibility and user feedback.
