Hygiene B0-B1: correctness & latent traps

- Restore swallowed [Test] on EnemyAIMathTests.SlideVelocity_DegenerateNormal_DeflectsToTangent (dead regression guard for the shipped enemy-stuck-on-cover fix; now runs + passes).
- Extract shared HarvestMath.DepositYield used by ResourceHarvestSystem + MeleeComboSystem; fixes melee mining silently ignoring per-item StackMax (it hard-coded DefaultStackMax) and hoists the melee ledger-buffer fetch out of the per-target loop.
- StatMath.Apply switches on the raw byte (case (byte)ModOp.X) instead of casting to the enum inside the Bursted fold — removes the latent cross-assembly enum-in-Burst ICE trap.
- Add [Min] guards on CycleDirectorAuthoring loss-critical ints (CoreIntegrityMax>=1 so a mis-authored 0 can't bake an instant-loss core; siege sizes >=0).

456/456 EditMode tests pass.
