Detailed Description

Tests for Aleph::CA metric helpers (Phase 7).

Scope:

• count_state, count_alive, density on rectangular and graph lattices.
• state_histogram and shannon_entropy edge cases.
• frame_hash determinism: identical frames hash the same; the hash is stable across an entire test process.
• frames_equal and cell_diff_count consistency with frame_hash.
• for_each_cell visits every cell in row-major order.
