Improve intent list output with table layout and skill hierarchy

[KyleAMathews]

Summary

• Replace flat skill listing with a two-section layout: a summary table (package/version/skill-count/requires) up top, then a skill tree below showing parent→child hierarchy via indentation
• Type tags ([core], [framework]) conditionally shown only when skills define them
• Column widths computed globally across all packages for consistent alignment

Before

Intent-enabled packages (3 found):

@tanstack/db v0.5.2
  db-core                           Core database concepts and collection setup
  db-core/live-queries              Reactive live queries with automatic re-evaluation
  db-core/optimistic-updates        Optimistic mutation patterns with rollback

After

3 intent-enabled packages, 11 skills (pnpm)

PACKAGE             VERSION  SKILLS  REQUIRES

@tanstack/db        0.5.2    4       –
