Subject: feat(shaders): Standardize all shaders to use CommonUniforms
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Define CommonUniforms struct with standard fields:
- resolution: vec2<f32>
- aspect_ratio: f32
- time: f32
- beat: f32
- audio_intensity: f32

Updated 14 shaders to use CommonUniforms:
- Replaced width/height with resolution
- Unified intensity/audio_peak → audio_intensity
- Moved effect-specific params to EffectParams struct
- visual_debug.wgsl now uses GlobalUniforms.view_proj

All shaders now have consistent uniform interface.
