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.

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

Add Delete, List, ListTopByIsland, and GetLineage methods to the programs
Store. These complete the CRUD operations needed for the evolution pipeline:
- Delete: Remove programs by ID
- List: Paginated listing of all programs
- ListTopByIsland: Get top N programs by fitness for a specific island
- GetLineage: Recursively traverse parent chain for lineage tracking
Also adds comprehensive tests for all new operations including lineage
tracking through grandparent-parent-child chains.
