Constant MIN_STAT_MOD_MULT

pub const MIN_STAT_MOD_MULT: f64 = 0.05;

Floor on a stat’s .mod multiplier in get_entity_stat, so a stacking .mod debuff (e.g. weakness on attack, protection on received_damage) can’t drive a stat to ≤0 (zero-damage / unkillable). 0.05 ⇒ ≤95% debuff. Only bites at mod ≤ −9500; no-mod / buff stats are unaffected.
