16 hours	fix(headless): add nullptr checks for GPU resource creation	skal
	- NodeRegistry::create_texture: skip texture creation when device is nullptr - Post-process helpers: skip pipeline/bind group creation in headless mode - SamplerCache: return nullptr for headless mode - BindGroupLayoutBuilder/BindGroupBuilder: skip creation with null device - RenderPipelineBuilder: skip shader module and pipeline creation in headless - PlaceholderEffect: skip sampler creation in headless mode - RotatingCubeEffect: early return in constructor for headless mode WIP: Some effects (GaussianBlur, etc.) still need headless checks Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
16 hours	refactor: remove v2 versioning artifacts, establish Sequence as canonical system	skal
	Complete v1→v2 migration cleanup: rename 29 files (sequence_v2→sequence, effect_v2→effect, 14 effect files, 8 shaders, compiler, docs), update all class names and references across 54 files. Archive v1 timeline. System now uses standard naming with all versioning removed. 30/34 tests passing. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
