Analyze UI change: display patterns separately, pull pattern-contained nodes out of the node list

[fangyangci]

Background

As the pattern decision logic is cleaned up (see #981), the analyze output UI needs to be adjusted so that patterns are clearly visible in the results.

Goals

• Display patterns separately: present each pattern as an independent unit in the analyze output.
• Pull the pattern's constituent nodes out of the node list: nodes covered by a matched pattern are no longer shown mixed into the regular node list, but grouped under their corresponding pattern instead.

To be confirmed

The exact UI changes (layout, grouping, fields, whether a pattern is expandable to view its internal nodes, etc.) still need further confirmation before being finalized.
