feat: add includeOperations to search_nodes and patterns mode to search_templates

- Add `includeOperations` flag to search_nodes that returns resource/operation
  trees per result (e.g., Slack: 7 resources, 44 operations). Saves a get_node
  round-trip when building workflows.
- Add `searchMode: "patterns"` to search_templates — lightweight workflow pattern
  summaries mined from 2,700+ templates (node frequency, co-occurrence, connection
  chains across 10 task categories).
- Fix operations extraction: use filter() instead of find() to capture ALL
  operation properties, each mapped to its resource via displayOptions.
- Fix FTS-to-LIKE fallback silently dropping search options.
- Add mine-workflow-patterns.ts script (npm run mine:patterns).
- Restore 584 community nodes in database after rebuild.
