Added HEADLESS_RETURN_IF_NULL/HEADLESS_RETURN_VAL_IF_NULL macros
that compile to no-ops in STRIP_ALL/FINAL_STRIP modes.
Files updated:
- fatal_error.h: New headless check macros
- sequence.cc: NodeRegistry::create_texture
- post_process_helper.cc: Pipeline creation functions
- sampler_cache.h: SamplerCache::get_or_create
- bind_group_builder.h: Layout/group builders
- pipeline_builder.h: Shader and pipeline builders
- All effect constructors (7 files)
Headless tests passing. STRIP_ALL builds will have zero overhead.

- 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

SamplerCache singleton never released samplers, causing device to retain
references at shutdown. Add clear() method and call before fixture cleanup.

Add BindGroupLayoutBuilder, BindGroupBuilder, RenderPipelineBuilder,
and SamplerCache to reduce repetitive WGPU code. Refactor
post_process_helper, cnn_effect, and rotating_cube_effect.
Changes:
- Bind group creation: 19 instances, 14→4 lines each
- Pipeline creation: 30-50→8 lines
- Sampler deduplication: 6 instances → cached
- Total boilerplate reduction: -122 lines across 3 files
Builder pattern prevents binding index errors and consolidates
platform-specific #ifdef in fewer locations. Binary size unchanged
(6.3M debug). Tests pass.
