refactor(wgsl): Use vec*f alias for vector types

Replaces all instances of `vec<f32>` with the more concise `vec*f` alias (e.g., `vec3f`) across all `.wgsl` shaders. This improves readability and aligns with common graphics programming conventions.

Also adds a new coding style rule to `doc/CODING_STYLE.md` to enforce this standard going forward.

Finally, this commit fixes a build error in `test_effect_base.cc` by replacing a call to the non-existent `wgpuDeviceTick` with `wgpuDevicePoll`, which resolves the test failure.

 - Functional style is clearer and less error-prone
 - `ptr<function, T>` adds complexity with no performance gain for small types
 
+### Vector and Matrix Type Aliases
+
+**Rule:** Use concise aliases for vector and matrix types (`vec3f`, `mat4x4f`) instead of the verbose generic form (`vec3<f32>`, `mat4x4<f32>`).
+
+```wgsl
+// Correct
+var p: vec3f;
+var m: mat4x4f;
+
+// Wrong
+var p: vec3<f32>;
+var m: mat4x4<f32>;
+```
+
+**Rationale:**
+- Improves readability and reduces visual noise.
+- Aligns with common graphics programming conventions.
