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).

Static arena with 20x20 floor and 4 box obstacles rendered using the
forward PBR pipeline with shadow mapping. Fixed quarter-view camera
at (0, 15, 10) looking at origin.

Interactive demo showing panel, text, button, slider, and checkbox
widgets rendered via the new UiRenderer pipeline. Uses winit event
loop with mouse input forwarded to UiContext.

Adds NetSocket (non-blocking UdpSocket wrapper with local_addr), NetServer
(connection tracking via HashMap, poll/broadcast/send_to_client), and NetClient
(connect/poll/send/disconnect lifecycle). Includes an integration test on
127.0.0.1:0 that validates ClientConnected, Connected, and UserData receipt
end-to-end with 50ms sleeps to ensure UDP packet delivery.

Fix pbr_demo, multi_light_demo, and shadow_demo to use the new 7-param
create_pbr_pipeline with PBR texture bind group (4-entry: albedo+normal)
and IBL bind group. Create ibl_demo showcasing a 7x7 metallic/roughness
sphere grid with IBL-based ambient lighting via BRDF LUT integration.

- Add Mat4::orthographic() to voltex_math for light projection
- Fix pbr_demo and multi_light_demo to provide shadow bind group (group 3)
required by updated PBR pipeline (dummy shadow with size=0 disables it)
- Create shadow_demo with two-pass rendering: shadow depth pass using
orthographic light projection, then PBR color pass with shadow sampling
- Scene: ground plane, 3 spheres, 2 cubes with directional light

7x7 grid of spheres demonstrating PBR material variation:
metallic increases along X axis, roughness along Y axis.
Uses dynamic UBO pattern for both camera and material uniforms.
