Homebrew 4D Game Engine In Rust, inspired by Engine4D

Port all consumers to new ECS API, remove Entity-based methods

- Remove from_entity(), add_entity(), add_entity_with_color() from RenderableGeometry (renderable.rs) - Remove Entity re-export from rust4d_render/src/lib.rs - Port all 4 examples to use world.spawn() with component tuples - Port physics_integration.rs tests to world.spawn() - Port renderable.rs tests to use from_world/add_components_with_color All 478 tests pass. Zero references to Entity struct remain in compiled code (only docs have stale references). Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
