- Add ZoneBounds type to bot state structs (Go, Rust, TypeScript)
- GathererBot now moves toward zone center when outside or near edge
- Bots can see zone bounds in fog-filtered state (per plan §3.7.1)
- Fixes gofmt formatting in types.go and bot_strategies.go
This improves bot survival and combat behavior by making them
zone-aware, preventing unnecessary zone deaths when the safe area
shrinks.

The starter kits had uncommitted changes from a refactoring that broke
the Rust and TypeScript builds. This commit completes the refactoring
and fixes the build errors.
**Rust starter fixes:**
- Add `http::header` import to fix `header::HeaderName` reference
- Replace `hmac::compare_digest` (non-existent) with constant-time comparison
**TypeScript starter fixes:**
- Rename `GameState` -> `VisibleState` and `MoveResponse` -> `TurnResponse`
- Fix `strategy.ts` to use `bot.position.row` instead of `bot.row`
- Fix Move type to use `position: {row, col}` structure
**Go starter fixes:**
- Remove unused `strings` import
All 8 starter kits now build successfully with their respective toolchains.

Complete Go starter kit for AI Code Battle with:
- main.go: HTTP server with HMAC authentication, placeholder computeMoves()
- game/ package: Shared utilities (types, auth, grid) for reuse
- types.go: Game state types, Direction constants, Position, etc.
- auth.go: HMAC-SHA256 signing/verification with timestamp validation
- grid.go: Toroidal distance, BFS pathfinding, neighbor functions
- Tests: Comprehensive test coverage for grid and auth utilities
- Dockerfile: Multi-stage build with Go 1.24-alpine
- README: Complete documentation with examples and protocol reference
The starter kit provides a minimal working bot that holds position
by default. Participants implement their strategy in computeMoves()
using the provided grid utilities.

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.

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.
