Port table layout and skill hierarchy to intent-library list

[KyleAMathews]

Summary

• Port the table + skill tree display from intent list (Improve intent list output with table layout and skill hierarchy #15) to the intent-library CLI
• Replace flat name description path listing with summary table (PACKAGE/VERSION/SKILLS) + hierarchical skill tree
• Both CLIs now share a consistent output format
