feat(cli): prompt to install skills during init (#206)

Replace the static "Tip" message at the end of `hyperframes init` with an
interactive prompt that offers to install AI coding skills. When the user
accepts, the skills command runs `npx skills add` with `--all` and
`stdio: "inherit"` so the native installer output is visible.
