Subject: [PATCH] Refactor batch processing system with shared QueueProcessor
 base class
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

• Created QueueProcessor base class for shared queue management, retry logic, and persistence
• Refactored BatchProcessor to extend QueueProcessor (385→142 lines, 63% reduction)
• Created BatchController with comprehensive API endpoints for batch operations
• Added Digital Ocean templates integration with caching
• Integrated batch endpoints into ManualServer with proper routing
• Fixed infinite recursion bug in queue status calculations
• Eliminated ~400 lines of duplicate code across processors
• Maintained backward compatibility with existing test interfaces

Architecture benefits:
- Single source of truth for queue processing logic
- Simplified maintenance and bug fixes
- Clear separation between AutoProcessor (production) and BatchProcessor (R&D)
- Extensible design for future processor types
