Heavy Bugfix

Fixes a vanilla Mycopunk bug where the Heavy upgrade's fire-rate roll range changes depending on equip/stack context, confusing players comparing copies.

The bug

Heavy's fire-interval property uses OverrideThenAdd. When building the tooltip stat list, the game converts that to either Override or Add based on how many Heavies are already equipped (GetAppliedCount), then runs it through StatData.CreateInverse against the weapon's fire interval.

On a weapon with fireInterval = 0.3 and Heavy's range 0.38–0.45, that yields:

The rolled value is still seed-based; only the bracket text was lying.

The fix

This mod patches UpgradeProperty_FireInterval.GetStatData so tooltips always:

1. Use first-copy (Override) display semantics for OverrideThenAdd
2. Use the gear prefab baseline fire interval (not live modified stats)

Combat application (Apply) is unchanged — stacking still works as designed.
