Pull request overview

This PR expands the app’s scenario/testcase system and UI, while also introducing multiple physics/rendering upgrades (constraints rendering, velocity arrows, buoyancy, updated collision/manifold code).

Changes:

• Reworks the UI flow in renderer/window.cpp (start screen/guide/menu bar) and adds theming/font loading.
• Refactors/extends scenarios (TestCase enum + scenario loader now returns a Camera) and adds new “chapterwise” scenario mappings.
• Updates physics engine internals (manifold/contact structures, constraint solving, collision manifold builders) and adds buoyancy support.

app/test_scenarios.cpp:374

• spawn_box_ramp_case now creates the ramp with a non-zero mass (2.0f). That makes the ramp dynamic, so it will fall under gravity and move during the scenario, which typically defeats the purpose of a ramp test setup. If the ramp is meant to be a static environment object, its mass should remain 0.0f.

        world.addBody(Rigidbody(Vec3(-2.0f, 0.0f, 0.0f), Vec3(0.0f, 0.0f, 0.0f), &g_gentle_ramp, 2.0f));
        world.addBody(Rigidbody(Vec3(0.5f, 4.0f, 0.0f), Vec3(0.0f, 0.0f, 0.0f), &g_small_box, 2.0f));
