Add metrics server startup and HTTP middleware to acb-api, generation
counter metric to evolver, and R2 cache size metric to index builder.
Also remove dead measureR2CacheSize reference from index builder main.

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 Exploration and Formation axis definitions with feature extraction
from source code pattern matching (exploration/formation indicators)
- Extend Grid key from (x,y) to (x,y,z,w) with 3⁴=81-cell behavior grid
- Update bin assignment, promotion gate, and persistence (JSON snapshot)
- Add Slice() for 2-D dashboard visualization across any axis pair
- Migration: old 2-D archives project at z=middle, w=middle
- Update cross-pollination to pad 2-element behavior vectors to 4
- Add Prometheus metrics to matchmaker (bot crashes, stale job count)
- Add rivalry detection to index builder (data/meta/rivalries.json)
- Web: batched bot list loading, leaderboard keyboard accessibility,
improved ARIA attributes on match/playlist cards

Adds cross-pollination logic that copies the top program from each island
to a random other island every 50 generations. When source and target
islands use different languages, the LLM translates the code. Generation
boundaries are tracked per-island to prevent duplicate events.
- New crosspoll package with boundary detection, migration, and LLM translation
- Added MaxGenerationByIsland DB query for generation counter tracking
- Integrated into RunEvolutionLoop with observability logging
- Tests for boundary logic, translation prompts, and target selection
