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.
