feat(intelligence): add self-evolution UI for identity change proposals

P1.1: Identity Change Proposal UI
- Create IdentityChangeProposal.tsx with diff view for SOUL.md changes
- Add approve/reject buttons with visual feedback
- Show evolution history timeline with restore capability

P1.2: Connect Reflection Engine to Identity Proposals
- Update ReflectionLog.tsx to convert reflection proposals to identity proposals
- Add ReflectionIdentityProposal type for non-persisted proposals
- Auto-create identity proposals when reflection detects personality changes

P1.3: Evolution History and Rollback
- Display identity snapshots with timestamps
- One-click restore to previous personality versions
- Visual diff between current and proposed content
