- Add pagination support to all template search/list tools
  - Consistent response format with total, limit, offset, hasMore
  - Support for customizable limits (1-100) and offsets

- Add new list_templates tool for browsing all templates
  - Returns minimal data (id, name, views, node count)
  - Supports sorting by views, created_at, or name
  - Efficient for discovering available templates

- Enhance get_template with flexible response modes
  - nodes_only: Just list of node types (minimal tokens)
  - structure: Nodes with positions and connections
  - full: Complete workflow JSON (default)

- Update database_statistics to show template count
  - Shows total templates, average/min/max views
  - Provides complete database overview

- Add count methods to repository for pagination
  - getSearchCount, getNodeTemplatesCount, getTaskTemplatesCount
  - Enables accurate pagination info
