Introduces the voltex_net crate (no external dependencies) with a binary
Packet protocol over UDP. Supports 6 variants (Connect, Accept, Disconnect,
Ping, Pong, UserData) with a 4-byte header (type_id u8, payload_len u16 LE,
reserved u8) and per-variant payload encoding. Includes 7 unit tests covering
all roundtrips and invalid-type error handling.

Introduces the voltex_ai crate with NavMesh, NavTriangle structs and
XZ-plane barycentric point-in-triangle helper. Includes find_triangle,
triangle_center, and edge_midpoint utilities with 4 passing tests.

Demonstrates two-pass deferred rendering: G-Buffer pass writes position,
normal, albedo, and material to 4 render targets; lighting pass composites
with 8 animated orbiting point lights plus a directional light using a
fullscreen triangle.

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

Fix pbr_demo to use LightsUniform/LightData instead of old LightUniform.
Create multi_light_demo with 5 PBR spheres (varying metallic), a ground
plane, 4 colored orbiting point lights, a directional fill light, and a
spot light from above.

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.
