G-buffer (Phase 1):
- Add NodeTypes GBUF_ALBEDO/DEPTH32/R8/RGBA32UINT to NodeRegistry
- GBufferEffect: MRT raster pass (albedo+normal_mat+depth) + pack compute
- Shaders: gbuf_raster.wgsl (MRT), gbuf_pack.wgsl (feature packing, 32B/px)
- Shadow/SDF passes stubbed (placeholder textures), CMake integration deferred
Training infrastructure (Phase 2):
- blender_export.py: headless EXR export with all G-buffer render passes
- pack_blender_sample.py: EXR → per-channel PNGs (oct-normals, 1/z depth)
- pack_photo_sample.py: photo → zero-filled G-buffer sample layout
handoff(Gemini): G-buffer phases 3-5 remain (U-Net shaders, CNNv3Effect, parity)

- NodeRegistry: skip external nodes (texture==nullptr) in ~NodeRegistry()
and resize() to avoid double-releasing views set via set_external_view()
- test_shader_assets: update PASSTHROUGH check to match #include pattern
handoff(Claude): 35/35 tests passing.

Replace _pad with noise field in UniformsSequenceParams, providing
effects with non-deterministic random values [0..1] updated each frame.

Converts all static_cast<>, reinterpret_cast<> to C-style casts
per CODING_STYLE.md guidelines.
- Modified 12 files across gpu, 3d, util, tests, and tools
- All builds passing, 34/34 tests passing
- No functional changes, pure style cleanup

Effects now accept start/end time parameters and automatically passthrough
when inactive. Implements buffer chain integrity via compile-time validation.
- Effect base class: dispatch_render() checks time bounds, auto-passthroughs
1:1 input/output effects outside [start, end] interval
- seq_compiler.py: validates producer/consumer lifespan constraints for
multi-output effects, adds --validate flag, always validates before codegen
- Updated all 9 effect classes and test fixtures to pass start/end times
- check_all.sh: includes timeline validation step
- Tests: 34/34 passing, demo runs successfully

Hybrid3D was calling Renderer3D::render() which creates its own command
encoder, bypassing the sequence system. Now uses renderer_.draw() with
the passed encoder.
Also adds texture blit support for RotatingCube compositing.

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

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.
