update ascii-video skill: design patterns, local time, examples

- New references/design-patterns.md: layer hierarchy (bg/content/accent),
  directional parameter arcs, scene concepts and visual metaphors,
  counter-rotating systems, wave collision, progressive fragmentation,
  entropy/consumption, staggered crescendo buildup, scene ordering
- New references/examples.md: copy-paste-ready scenes at every complexity
- Update scenes.md: local time convention (t=0 at scene start)
- Update SKILL.md: add design-patterns.md to reference table
- Add README.md to hermes-agent copy
- Sync all reference docs with canonical source (SHL0MS/ascii-video)
