Add sitemap.xml generation as a final pass in the index builder. The
sitemap covers all public pages: home, leaderboard, bots list, bot
profiles, matches list, featured replays, seasons, rivalries,
predictions, and docs.
- Add SiteURL config field (ACB_SITE_URL env var, defaults to
https://aicodebattle.com)
- Add generateSitemap() function with proper XML encoding
- Add SitemapURL and Sitemap types for XML marshaling
- Call generateSitemap() at the end of generateAllIndexes()
- Write sitemap.xml to output directory alongside leaderboard.json

Replace random 2-player pairing with the full §6.1 algorithm:
- Seed selection: bot with oldest last-match timestamp (tiebreak: lowest bot ID)
- Format selection: seed's least-played player count among {2, 3, 4, 6}
- Opponent selection: Pareto 80%/16-rank skill proximity + oldest last-pairing
with seed + fewest 24h games for game-count balance
- Map selection: least-recently-used active map for the chosen player count,
with map_scores.last_used_at updated after each match
- Random player slot assignment for all participant counts

Per plan §11.1, the index builder reads PostgreSQL and generates all JSON
index files for Cloudflare Pages deployment:
- main.go: Build cycle orchestration with configurable timeout, self-restart
- config.go: Environment-based configuration with sensible defaults
- db.go: PostgreSQL data fetching for bots, matches, series, seasons, predictions
- generator.go: JSON index generation (leaderboard, bots, matches, playlists)
- deploy.go: Cloudflare Pages deployment via wrangler, R2 warm cache pruning
- Dockerfile: Multi-stage build with Go + Node.js + wrangler CLI
- main_test.go: Tests for config, index generation, playlists
Index builder runs on 15-minute cycles, deploys to Pages every ~90 minutes,
and prunes R2 warm cache weekly to stay within 10GB free tier.
