feat: add includeOperations to search_nodes and patterns mode to search_templates

Browse Source 
- 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.

## [Unreleased]
## [2.42.0] - 2026-03-30
### Added
- **`includeOperations` flag for search_nodes**: Opt-in parameter that returns a resource/operation tree per search result, grouped by resource (e.g., Slack returns 7 resources with 44 operations). Saves a mandatory `get_node` round-trip when building workflows. Adds ~100-300 tokens per result.
- **`searchMode: "patterns"` for search_templates**: New lightweight mode that serves workflow pattern summaries mined from 2,700+ templates. Returns common node combinations, connection chains, and frequency data per task category (10 categories: ai_automation, webhook_processing, scheduling, etc.). Use `task` parameter for category-specific patterns or omit for overview.
- **Workflow pattern mining script** (`npm run mine:patterns`): Extracts node frequency, co-occurrence, and connection topology from the template database. Two-pass pipeline: Pass 1 analyzes `nodes_used` metadata (no decompression), Pass 2 decompresses workflows for connection analysis. Produces `data/workflow-patterns.json` with 554 node types, 3,201 edges, and 5,246 chains.
### Fixed
- **Operations extraction now includes resource grouping**: The property extractor was using `find()` to get only the first `operation` property, but n8n nodes have multiple operation properties each mapped to a different resource via `displayOptions.show.resource`. Changed to `filter()` to capture all operation properties. Slack went from 17 flat operations to 44 operations across 7 named resources.
- **FTS-to-LIKE fallback dropped search options**: When the FTS5 search fell back to LIKE-based search (e.g., for "http request"), the `options` object (including `includeOperations`, `includeExamples`, `source`) was silently lost. Now correctly passed through.
