initial: actor v0.1.0 — composition-wrapper + movement-speed-contract

Phase-A.5 implementation per
sporel-meta/docs/superpowers/specs/2026-06-09-phase-A-...
Re-Entry from P.0-Actor-Deferral (Trigger 1: Composition-Aktivierung).

Slim wrapper: actor.create validates properties.movement_speed > 0,
delegates to composition.create. actor.position reads dotted position
back as two numbers. actor.move does direct inert-write to position.x
+ position.y (engine §11 inert-write; Action-routing deferred).

DEFERRED in v0.1: Body-Slot-Aggregator, Walk-Capability, Movement-State
on entity, Action-mediated move. All have re-entry-trigger notes.
