Detailed Description

Phase 14 tests for multi-field CA lattices, rules and engine.

Coverage:

• AoS vs SoA equivalence on a discrete predator-prey rule (frame must match bit-by-bit at every step).
• Per-field SoA buffer is reachable as a regular Lattice and can be handed to the legacy Synchronous_Engine.
• Lotka-Volterra continuous rule on a 64×64 toroidal grid stays bounded and exhibits a population cycle.
• Gray-Scott reaction-diffusion migrated from the Phase 9 monolithic Reaction_Diffusion_Cell rule to a multi-field (u, v) rule produces frames that match the monolithic output to within a tight numerical tolerance.
• Field_Slice_Rule propagates the untouched fields verbatim.
