feat(explain): complete Explain API integrations (plan §13.20)
Complete all TODO integrations in explainer.rs for query explain output: - Alias lookup in task store with version info - Tenant affinity resolution with hash fallback - EWMA latency from replica selection - Comprehensive test coverage for all integrations - Updated miroir-ctl explain command with full output formatting Closes: bf-5pico Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
