Scale gas spread, weapon refill, litter size, and post-mating stop with difficulty
Four gameplay parameters are now driven by the selected difficulty, following the existing 'hard = harder for the player' philosophy: param easy normal hard gas_spread_speed 40 50 90 (higher = slower gas) weapon_refill_multiplier 1.3 1.0 0.6 (less ammo on hard) max_babies 2 3 5 (more pups on hard) mate_stop_male / female 120/240 100/200 60/120 (shorter stop on hard) Implementation: - engine/config.py: new keys on each DIFFICULTY_OPTIONS entry. - rats.py: _apply_difficulty() loads them onto the game (with __init__ defaults for safety); normal keeps the previous hardcoded values. - units/gas.py: Gas.speed reads game.gas_spread_speed (fallback 50). - engine/unit_manager.py: refill_ammo() scales per-frame refill chances by game.weapon_refill_multiplier (fallback 1.0). - units/rat.py: Male.fuck() uses game.mate_stop_male/mate_stop_female and random.randint(1, game.max_babies) (fallbacks to old values). All reads use getattr with the previous constant as fallback, so older configs / saved state keep working.
