Complete batch 012 (golden set diff) and 013 (advisory chat), fix build errors
Sprints completed: - SPRINT_20260110_012_* (golden set diff layer - 10 sprints) - SPRINT_20260110_013_* (advisory chat - 4 sprints) Build fixes applied: - Fix namespace conflicts with Microsoft.Extensions.Options.Options.Create - Fix VexDecisionReachabilityIntegrationTests API drift (major rewrite) - Fix VexSchemaValidationTests FluentAssertions method name - Fix FixChainGateIntegrationTests ambiguous type references - Fix AdvisoryAI test files required properties and namespace aliases - Add stub types for CveMappingController (ICveSymbolMappingService) - Fix VerdictBuilderService static context issue Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
