feat: Institutional knowledge vision + roadmap phases 11-15
## Vision Update
- Shift from "code-level truth linter" to "self-learning institutional knowledge"

- Commit only → 0.40 authority, 10 usages
- Three-tier knowledge: Policies → Conventions → Observations
- Knowledge compounds with every commit
## Gap Analysis
- Documented missing features for enterprise pilot
- Phases 11-15 spec with implementation details

## Roadmap Additions
- Phase 11: Evidence-Based Authority (🎯 current)
- Phase 12: Knowledge Scope Hierarchy
- Phase 13: Knowledge Lifecycle Management
- Phase 14: Governance Workflows
- Phase 15: Evidence Source Integration
## Enterprise Simulation UAT
- 6-month simulation: 3 teams, 19 contributors
- Month-by-month scenarios with expected outcomes
