Meta Vens 450d0731f7 Add presenter interfaces and a capability event binder
IAbsorbPresenter/IGrabPresenter/IMeleePresenter/IThrustPresenter let a Unity
component declare which capability events it visualizes without knowing about
CapabilityEvents itself. CapabilityPresentationBinder is the only thing that
subscribes a presenter to its matching stream, resolving a GrabEvent's plain
target handle to a live Transform (and initial velocity) through delegates its
owner supplies, since the engine-free GrabEvent can't carry a Unity reference.
Neither file knows about FieldDriver or any other concrete presentation.

// Presentation-side contract for the capability events in Assets/Scripts/ServerShared/CapabilityEvents.cs

// match what it visualizes -- one presentation may implement all four (the field shield), or just one
// (a dedicated melee-blade effect). CapabilityPresentationBinder is what actually wires a presenter's
// method to the matching event stream; a presenter never talks to CapabilityEvents itself.

// TargetHandle is a plain identity, not a Unity reference). The binder resolves the handle through a
// delegate supplied by the event source's owner and hands the presenter the result, along with the
// initial velocity the target was already moving with (also owner-supplied, for the same reason).
