refactor(world): extract live projection mechanics

Browse source 
Move appearance rebinding, collision construction, default-pose resolution, local shadow ownership, and exact leave-world presentation into focused owners. Preserve retail parent ordering with staged validation, committed recovery, recursive attached-subtree withdrawal, and retryable exact teardown across parent, pickup, position, unwield, and pose-loss edges.
