feat(effects): add Scratch post-process effect with reusable scratch_lines snippet
- src/shaders/render/scratch_lines.wgsl: reusable WGSL snippet registered as
"render/scratch_lines"; call scratch_lines(uv, resolution, time)->f32 from
any effect. Uses hash_1f from math/noise; 8 lines/frame, ~24fps flicker.
- src/effects/scratch.{wgsl,h,cc}: thin Scratch effect wrapping the snippet.
- Applied to "intro" and "rotating_cube" sequences as the final step.
- 35/35 tests passing.
handoff(Gemini): Scratch effect added. render/scratch_lines snippet is reusable.
