feat: Phase 9.78e complete - instance_v2 migration with legacy compatibility
- instance_v2 now includes legacy compatibility layer - All interpreter code migrated to use instance_v2 - Added legacy field access methods (get_fields, set_field_legacy, etc.) - Fixed type conversion issues (NyashValue vs SharedNyashBox) - instance.rs still exists but no longer used in interpreter - TODO: Remove instance.rs completely in next phase - TODO: Implement proper SharedNyashBox -> NyashValue conversion 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
