Subject: [PATCH] feat(agent): implement advanced debugging features in
 EmulatorService

- Added methods for managing breakpoints, including adding, removing, listing, and enabling/disabling breakpoints.
- Introduced watchpoint management methods, although integration is pending.
- Implemented execution control features such as stepping through instructions and running to breakpoints.
- Enhanced disassembly capabilities to retrieve and display instruction details from memory.
- Updated header file to include new debugging functionalities, ensuring clarity and modularity.

Benefits:
- Improved debugging capabilities for the emulator, facilitating better development and testing workflows.
- Enhanced user experience by providing detailed control over execution and memory analysis.
