Skill (hyperframes-cli): three-pattern table (cutout-over-different-scene
vs over-its-own-source vs over-different-take) + the two non-obvious rules
(wrap video in non-timed div for opacity control, both videos data-start=0
for sync). Skill (hyperframes/patterns): worked text-behind-subject example.
Docs: --quality flag, compositing pitfalls section, quality preset table.

Adds `hyperframes remove-background` — a local-AI subcommand that mattes a
video or image with the u2net_human_seg ONNX model and emits a transparent
WebM (VP9-alpha), ProRes 4444 .mov, or RGBA PNG. Drops directly into any
composition's <video> tag — no green screen, no API keys, no upload.
Auto-picks the fastest available execution provider via onnxruntime-node:
CoreML on Apple Silicon, CUDA when HYPERFRAMES_CUDA=1, CPU otherwise.
