feat: include tap attributes in cmd-K full-text search

Add attributes_text flattened field to OpenSearch indexing for both
execution and processor levels. Include in full-text search queries,
wildcard matching, and highlighting. Merge processor-level attributes
into ExecutionSummary. Add 'attribute' category to CommandPalette
(design-system 0.1.17) with per-key-value results in the search UI.
