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.

Add friction coefficient to RigidBody (default 0.5) and implement
tangential impulse clamping in resolve_collisions using Coulomb's law,
including resting-contact friction for sliding bodies.

Implement GJK (Gilbert-Johnson-Keerthi) overlap detection and EPA
(Expanding Polytope Algorithm) penetration resolution for arbitrary
convex collider pairs. Used as the fallback narrow phase for any
combination involving Capsule, while Sphere/Box specialized routines
are preserved for performance.

Add Capsule { radius, half_height } to the Collider enum, with AABB
computation and ray-vs-capsule intersection support. The capsule is
oriented along the Y axis (cylinder + two hemisphere caps).

Parse PNG files (RGB and RGBA, 8-bit) with full filter reconstruction
(None, Sub, Up, Average, Paeth). Uses the self-contained deflate
decompressor for IDAT chunk decompression.

Add UiRenderer with wgpu render pipeline for 2D UI overlay rendering.
Includes WGSL shader with orthographic projection, alpha blending,
and R8Unorm font atlas sampling. Font pixel (0,0) set to white for
solid-color rect rendering via UV (0,0).
