Stats Dashboard Page (/stats)

[MarkusNeusinger]

Feature: Public Stats Dashboard

A public /stats page that meta-visualizes the platform's own data — a data viz site showing stats about its data viz.

What it shows

• Summary counters: total specs, total implementations, total lines of code, avg quality score
• Per-library bar chart: avg quality score, implementation count (pure CSS bars)
• Coverage heatmap: spec rows x library columns, cells colored by quality score (clickable)
• Score distribution histogram: 10 buckets (0-100)
• Top 10 implementations leaderboard (score >= 95)
• Tag distribution: most common plot types, domains, features
• Timeline: implementations per month

Technical Approach

• New router: api/routers/insights.py with GET /insights/dashboard
• Reuses SpecRepository.get_all() with stale-while-revalidate caching
• Frontend: app/src/pages/StatsPage.tsx (lazy-loaded)
• All visualizations rendered as MUI Box elements (no chart library)
