- Add test_cnn_v3_parity.cc: zero_weights + random_weights tests
- Add gen_test_vectors.py: PyTorch reference implementation for enc0/enc1/bn/dec1/dec0
- Add test_vectors.h: generated C header with enc0, dec1, output expected values
- Fix declare_nodes(): intermediate textures at fractional resolutions (W/2, W/4)
using new NodeRegistry::default_width()/default_height() getters
- Add layer-by-layer readback (enc0, dec1) for regression coverage
- Final parity: enc0 max_err=1.95e-3, dec1 max_err=1.95e-3, out max_err=4.88e-4
handoff(Claude): CNN v3 parity done. Next: train_cnn_v3.py (FiLM MLP training).

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)

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

Removed redundant and obvious comments from 7 GPU headers:
- post_process_helper.h: binding comments, stale UniformsSequenceParams note
- shader_composer.h: verbose Compose/VerifyIncludes descriptions
- uniform_helper.h: obvious method comments
- effect.h: redundant render/resize comments
- gpu.h: verbose struct/header comments, GPU perf placeholder
- sdf_effect.h: obvious method comments
- sequence.h: duplicate header, obvious API comments
Kept only non-obvious context (binding conventions, headless mode notes).

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.

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.
