sync: editable workflows from private repo

- Users can edit/create workflows from Settings → Workflows tab
- File-based storage for custom workflows
- Bundled workflows serve as fallback when no user file exists
- Added createEdge tool access for workflows (Quick Link)
- Cleaned up stale terminology in workflow prompts

 CRITICAL RULES
-- Search the FULL database, not just pinned nodes
+- Search the FULL database, not just top nodes
 - Use entities from step 1 to guide searches in step 2
 - Call updateNode EXACTLY ONCE - after success, move to step 5 immediately
 - Keep total tool calls ≤ 18 (be efficient)
