// getGlobalSkillsBase('kilo') was returning ~/.config/kilo/skills (the XDG
// config dir) instead of ~/.kilo/skills — where Kilo Code actually discovers
// global skills per its docs:
//   https://kilo.ai/docs/customize/skills
//   "Global skills are located in the `.kilo` directory within your Home
//    directory: ~/.kilo/skills/"
//
// The fix adds a special case in getGlobalSkillsBase() that resolves kilo's
// skills dir from HOME (not from the XDG config dir). The config dir at
// ~/.config/kilo is still CORRECT for commands (command/) and must stay
// unchanged — this test verifies both roles are separate.
