- Consume nerve before energy in CrimeService so energy is never lost when nerve is insufficient
- Initialize nerve/max_nerve from config in CharacterController::store (same pattern as energy/health)
- Add nerve_cost to all CrimeSeeder entries proportional to difficulty (1-5 range)
- Remove nerve_regen_at from Character $fillable/$casts/@property — column exists but is not yet wired up
