refactor(skills): rename graphic-overlays skill to talking-head-recut (#1720)

Rename the `graphic-overlays` workflow skill to `talking-head-recut`:

- move skills/graphic-overlays/ -> skills/talking-head-recut/
- update SKILL.md frontmatter name, H1, and self-references
- update all /graphic-overlays route references (hyperframes router,
  general-video, root + cli-template AGENTS.md/CLAUDE.md, docs, quickstart)
- update telemetry --skill flag, example composition id, timeline key
- update .prettierignore path and scripts/test-skills-fresh.sh

Identifier-only rename: the graphic-overlay card mechanism, design
references, and trigger wording are unchanged.
