docs(gpu): Purge comment bloat from GPU headers

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).
