Add ConvexHull struct storing vertices with a support function that
returns the farthest point in a given direction, enabling GJK/EPA
collision detection. Update all Collider match arms across the physics
crate (collision, raycast, integrator, solver) to handle the new variant.

Add serialize/deserialize methods directly on NavMesh with a proper
binary header (magic "VNAV" + version u32) for format validation.
Includes tests for roundtrip, invalid magic, empty mesh, header format,
and unsupported version.

Add per-component tick tracking to SparseSet. Insert and get_mut mark
the current tick; increment_tick advances it. World gains query_changed
to find entities whose component changed this tick, and clear_changed
to advance all storages at end of frame.

Add GltfNode, GltfSkin, GltfAnimation, GltfChannel structs and parsing
for skeletal animation data. Extend GltfMesh with JOINTS_0/WEIGHTS_0
attribute extraction. All existing tests pass plus 4 new tests.

Add ttf_font field to UiContext with draw_text and ttf_text_width
helpers that use TTF when available, falling back to bitmap font.
Load system TTF font (arial/consola/malgun) in editor_demo on startup.

Render actual 3D geometry (cubes + ground plane) in the Viewport panel
using the existing mesh_shader.wgsl Blinn-Phong pipeline with orbit
camera controls (left-drag to orbit, middle-drag to pan, scroll to zoom).

Add full-frame-cycle integration test to dock.rs (16 tests total) and
update editor_demo to use DockTree layout instead of a single panel.

Add Simple Stupid Funnel (SSF) algorithm for optimal path smoothing through
triangle corridors. Refactor A* to expose find_path_triangles for triangle
index paths. Add binary serialize/deserialize for NavMesh and shared_edge
query method.

- Angular velocity integration with diagonal inertia tensor (sphere/box/capsule)
- Angular impulse in collision solver (torque from off-center contacts)
- Sequential impulse solver with configurable iterations (default 4)
- Sleep/island system: bodies sleep after velocity threshold timeout, wake on collision
- Ray vs triangle intersection (Moller-Trumbore algorithm)
- raycast_all returning all hits sorted by distance
- BVH query_pairs replaced N^2 brute force with recursive tree traversal
- BVH query_ray for accelerated raycasting
- BVH refit for incremental AABB updates
- Swept sphere vs AABB continuous collision detection (CCD)
