add stepping functionality (Continue, Step Over, Step In, Step Out) and breakpoint management (Toggle individual, Clear all), providing a full-featured debugging experience for NWScript execution.

✅ Implemented Debugger TODO Features

1. Step In Functionality

• Implementation: Added btnStepIn() function that sends IPCMessageType.Debug with subType IPCMessageTypeDebug.ScriptStepIntoInstruction
• Button: Added Step Into Instruction button with appropriate FontAwesome icon (down arrow)

2. Step Out Functionality

• Implementation: Added btnStepOut() function that sends IPCMessageType.Debug with subType IPCMessageTypeDebug.ScriptStepOutInstruction
• Button: Added Step Out of Instruction button with appropriate FontAwesome icon (up arrow)

3. Clear Breakpoints Functionality

• Implementation: Added comprehensive btnClearBreakpoints() function that:
  • Iterates through all current breakpoints in instance.breakPoints
  • Sends IPCMessageType.RemoveScriptBreakpoint messages for each breakpoint with proper parameters (instance UUID + address)
  • Clears the breakpoints from the instance Map
  • Updates local state to trigger UI re-render
• Button: Existing Clear Breakpoints button now fully functional

4. UI Enhancements

• Imports: Added IPCMessageTypeDebug import for debug sub-types
• Button Layout: Integrated Step In and Step Out buttons into the main debugger controls between Step Over and Clear Breakpoints
• Icons: Proper FontAwesome SVG icons for all debugging buttons

Technical Details

IPC Message Patterns

• Step In/Out: Uses IPCMessageType.Debug with debug sub-types (following existing pattern)
• Clear Breakpoints: Uses IPCMessageType.RemoveScriptBreakpoint with parameters (instance UUID, address)

State Management

• Properly updates both instance state and local React state for breakpoints
• Maintains consistency between debugger backend and UI

Error Handling

• All functions check for valid instance before proceeding
• Graceful handling of empty breakpoint collections

Code Quality

• ✅ No linter errors
• ✅ Follows existing code patterns and conventions
• ✅ Comprehensive implementation with proper error handling
• ✅ Maintains backward compatibility

The debugger now has complete stepping functionality (Continue, Step Over, Step In, Step Out) and breakpoint management (Toggle individual, Clear all), providing a full-featured debugging experience for NWScript execution.
