Add Go index builder (cmd/acb-index-builder)

Browse source 
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.

**Status: 🔄 In Progress**
**Last Updated: 2026-03-29**
**Last Updated: 2026-03-29** (Go index-builder implementation)
### Recent Changes (2026-03-29)
- **Go Index Builder** (`cmd/acb-index-builder/`): New Go implementation per plan §11.1:
- Reads PostgreSQL, generates all JSON index files (leaderboard, bots, matches, series, seasons, playlists)
- `deployToPages()`: Cloudflare Pages deployment via wrangler CLI
- `pruneR2Cache()`: Weekly R2 warm cache pruning to stay within 10GB free tier
- `promoteRecentReplays()`: Copies recent replays from B2 cold archive to R2 warm cache
- Build cycle with configurable timeout (default 10m)
- Self-restarting after max lifetime (default 4h)
- Multi-stage Dockerfile with Node.js + wrangler for Pages deployment
- Comprehensive tests for config loading, leaderboard/bot/match index generation, playlists
- **Phase 9 Map Evolution Pipeline**: Added `cmd/acb-map-evolver/`:
- Parent selection weighted by engagement × vote multiplier from PostgreSQL
- Crossover breeding with sector-based wall inheritance
- Symmetry-preserving mutation (wall flips 5-10%, energy node shifts)
- Cellular automata smoothing for natural wall structures
- Validation: BFS connectivity, wall density (5-30%), area per player (900-5000 tiles)
- Smoke test validation with energy node accessibility checks
- PostgreSQL tables: `maps`, `map_votes`, `map_fairness` for lifecycle management
- Map statuses: active, probation, retired, classic per plan §14.6
- **Phase 7-9 Implementation**: Committed extensive feature work spanning evolution,
enhanced features, and platform depth:
- Phase 7: Evolution live-export for dashboard JSON generation
