New /analytics route: token usage dashboard with aggregate summary, per-session breakdown, context window stats, and per-category token distribution. Data served from existing agent_sessions + tool_cost_stats. New /results route: browsable archive of orchestrator flow runs and arena battles. Two-tab layout (Analysis Runs / Arena Battles) using existing API endpoints (no new backend). Sidebar gains Results (ScrollText icon) and Token Analytics (BarChart3 icon) nav buttons above Settings.
