feat(demo-01): Implement recursive mini-breakdown for goto resolution

The Goto Resolution step now shows a full breakdown of how the target
keyword's rules are applied, mirroring the main Pattern Matching,
Decomposition, and Template Selection steps:

- Shows "goto <keyword>" redirect statement in standard box styling
- Displays "Processing <keyword>" section with:
  - Pattern Matching: tests target keyword's patterns against input
  - Decomposition: shows captures if the pattern has wildcards
  - Template Selection: dropdown to select from available responses
- Changes propagate through Post-substitutions and Final Response
- Pattern testing uses matchPattern() with synonyms support
- Expandable pattern tests list when target has multiple patterns
