Module physics_lane 

Physics Lane.

After the Phase A refactor, StandardPhysicsLane is a thin wrapper around [PhysicsProvider::step]: it does no World queries and no structural mutations. The surrounding work is split into three Substrate-Pass stages:

1. [khora_data::flow::PhysicsFlow::adapt] — AGDF detach/reattach plus the ECS → provider sync (sync_to_world-equivalent) that feeds the simulation its inputs.
2. This lane — provider.step(dt). Pure simulation, no World access at all.
3. [khora_data::ecs::systems::physics_world_writeback] — pulls the new transforms, kinematic results, and collision events back into the World during the Maintenance phase.
