feat: implement Operation Protocol Improvements (OPI) architecture

- Add OPI registry system for extensible operation processing
- Implement IntermediateState and Context for secure state management
- Add BaseProcessor abstract class for OPI implementations
- Create test OPI processor as reference implementation
- Integrate OPI system with existing BRC20 indexer
- Add comprehensive test suite for OPI functionality
- Fix code quality issues and ensure all tests pass
- Update CI/CD pipeline configuration
- Add decimal conversion utilities for precise amount handling
- Implement marketplace transfer prioritization
- Add performance monitoring and security scanning
- Reorganize test structure for better maintainability
- Fix security vulnerabilities (authlib upgrade)
- Resolve safety tool compatibility issues

This commit introduces a complete OPI (Operation Protocol Improvements)
architecture that allows for extensible operation processing while
maintaining backward compatibility with existing BRC20 functionality.
