FieldTester now owns a CapabilityEvents instance and stands in for the
capability source the simulation doesn't have yet: it publishes AbsorbEvent
on click (cycling DamageType so the operator can see how a type-aware
presenter would behave), GrabEvent(Started) on pickup click, MeleeEvent on
the Melee button, and a ThrustEvent every frame from input -- FieldDriver only
ever reacts through CapabilityPresentationBinder. The damped push/twist state
that used to live directly on FieldDriver.Push/FrontTwist/RearTwist now lives
in FieldTester and is applied through the event instead.
Adds a CapabilityPresentationBinder component to the field object in
FieldShieldTest.unity, alongside the existing added ClickableCollider
component on that same prefab-instance GameObject (same pattern, no
serialized fields to wire). Scene behavior is unchanged: hits, melee, pickups
and flow all look and act as before.
