Updated all affected documentation files:
- UNIFORM_BUFFER_GUIDELINES.md: New CommonUniforms example
- ARCHITECTURE.md: Beat-based timing section
- EFFECT_WORKFLOW.md: Available uniforms reference
- CONTRIBUTING.md: Updated uniform buffer checklist
handoff(Claude): Beat-based timing system fully implemented and documented.

Root cause: Uniform buffers created but not initialized before bind group
creation, causing undefined UV coordinates in circle_mask_compute.wgsl.
Changes:
- Add get_common_uniforms() helper to Effect base class
- Refactor render()/compute() signatures: 5 params → CommonPostProcessUniforms&
- Fix uninitialized uniforms in CircleMaskEffect and CNNEffect
- Update all 19 effect implementations and headers
- Fix WGSL syntax error in FlashEffect (u.audio_intensity → audio_intensity)
- Update test files (test_sequence.cc)
Benefits:
- Cleaner API: construct uniforms once per frame, reuse across effects
- More maintainable: CommonPostProcessUniforms changes need no call site updates
- Fixes UV coordinate bug in circle_mask_compute.wgsl
All 36 tests passing (100%)
handoff(Claude): Effect API refactor complete

Fix EFFECT keyword format across all documentation and scripts - priority
modifier (+/=/–) is required but was missing from examples.
**Documentation fixes:**
- doc/HOWTO.md: Added missing + to EFFECT example
- doc/RECIPE.md: Added priority modifiers to examples
- tools/shadertoy/README.md: Fixed test path, clarified workflow
- tools/shadertoy/convert_shadertoy.py: Updated output instructions
**New automation guide:**
- doc/EFFECT_WORKFLOW.md: Complete step-by-step checklist for AI agents
- Exact file paths and line numbers
- Common issues and fixes
- Asset ID naming conventions
- CMakeLists.txt dual-section requirement
- Test list instructions (post_process_effects vs scene_effects)
**Integration:**
- CLAUDE.md: Added EFFECT_WORKFLOW.md to Tier 2 (always loaded)
- doc/AI_RULES.md: Added "Adding Visual Effects" quick reference
- README.md: Added EFFECT_WORKFLOW.md to documentation list
**CMakeLists.txt:**
- Disabled incomplete cube_sphere_effect.cc (ShaderToy conversion WIP)
**Timeline:**
- Commented out incomplete CubeSphereEffect
- Removed obsolete constructor argument
Fixes #issue-with-effect-syntax
