  saved it to configuration/manifest files.
• Emphasize (bold) actual skill names in interactive dialog options.
• Add a --version flag.
• JSON encode descriptions in the create command.
• Make list command more consistent with other commands and more informative:
  • Add agent aliases to agent labels (e.g., generic (antigravity, codex)).
  • Display actual install directory for each agent in the list header.
  • Add a note that listed skills are managed skills and additional skills may be installed.
  • Store relative repository paths in manifest and display in list output.

  repositories for skills.
• Support hyphens instead of underscores in package name prefixes when matching
  and creating skills.
• Update wording slightly for selection dialogs.

  prompted again in the source-selection dialog.
• Prompt user during skills prune (and after skills get) to remove local or
  global git repository sources that have no installed skills.
