Issue #70: NCA 15K (grid=9, states=9, G4 entropy) #525

Task

Implement NCA (Neural Circuit Analysis) for 15K steps.

Config

• Grid = 9
• States = 9
• G4 entropy = [1.5, 2.3]

Acceptance Criteria

• NCA implementation for 15K steps
• Grid=9, states=9
• G4 entropy constraints [1.5, 2.3]
• Save results to experiments/nca/15k/

Refs

• EXP-001: Trinity physics
