Hygiene B4a: extract shared FeedbackFx (dedup 4 procedural-FX copies)

Browse Source 
New FeedbackFx static (MakeClip/MakeParticleMaterial/MakeBurst/PlayClip/EmitTinted/EmitAt); the 3 *FeedbackSystem copies + AmbientAudio.MakeSting now route through it via 'using static'. MakeBurst takes the FX-root + the per-use gravity/radius/sizeTail that were the only diffs between copies; MakeClip folds in noise + decay. Behaviour-identical by construction (every particle/clip param preserved exactly).

459/459 EditMode tests pass; compiles clean. VFX are presentation-only (no EditMode coverage) -> wants a Play-mode smoke to eyeball hit/death/harvest/structure bursts.
