Add starters/php/ with complete starter kit for AI Code Battle:
- index.php: HTTP server with HMAC verification, routing for /turn and /health
- strategy.php: Stub compute_moves() function with example energy-seeking logic
- game.php: Game state types (GameState, Position, VisibleBot, etc.) and grid utilities (toroidal_manhattan, toroidal_chebyshev, bfs, neighbors, cardinal_steps)
- Dockerfile: Alpine-based PHP 8.4 container
- README.md: Quickstart documentation with local/Docker run instructions
- composer.json: Minimal composer config (no external dependencies)
Follows same contract as other starters:
- Listens on port 8080 (BOT_PORT env var)
- POST /turn: Receives game state JSON, returns moves JSON
- GET /health: Health check endpoint
- HMAC-SHA256 signature verification on requests/responses
Reference implementation: bots/guardian/ (GuardianBot in PHP)

- Add ReplayPlayer to type imports in replay-viewer.ts
- Add explicit type annotation for entry parameter in replay.ts transcript map
- Fixes TypeScript compilation errors for §15.3 screen reader transcript feature
- SeasonID and RulesVersion already present in engine/types.go Config struct
- Worker already populates from active season row via DB join
- Config embedded in VisibleState sent to bots each turn (including turn 0)
- All starter kits (go, python, rust, java, csharp) already expose and log fields
- Add season_id/rules_version logging to JavaScript starter on turn 0
- TypeScript Config interface already includes season_id and rules_version

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

Add crosspoll_state table to persist per-island generation counters
across evolver restarts. Load state on startup and save after each
cross-pollination check. Add persistence pattern and translation
structure tests.

Replace plain String.equals() with MessageDigest.isEqual() for
constant-time HMAC signature comparison. Switch from manual StringBuilder
JSON to Jackson ObjectMapper. Add typed Java records for game state,
moves, and config.

Add forkable starter kit templates for Python, Go, JavaScript, Rust,
Java, and C# — each with HTTP server scaffold, HMAC auth, game types,
random strategy, Dockerfile, and GHCR workflow. Update /compete/docs
page with starter kit links and registration instructions.
