The GSAP family README described HyperFrames as a 'future' engine ('if the
parallel HyperFrames engine gets wired in', 'becomes a day-1 skill', 'Future
hyperframes_compose tool — if added'). Every other artifact (AGENT_GUIDE.md,
skills/core/hyperframes.md, skills/INDEX.md) treats HyperFrames as a fully
production composition runtime, and hyperframes_compose is a registered tool.
Update the HyperFrames references to present-tense production reality. Also add
a scope note: this directory has no SKILL.md and is not a loadable skill — it
is a navigation map for the sibling gsap-* skills, which removes the ambiguity
about why it is not loadable via agent_skills[].
Closes #61
