@cursoragent fix all reported issues.

[cursor]

I enhanced the komodo_mcp_server by adding a command-line option to control stdio transport, improving the wallet.get_public_keys API response format, and making the application's dispose lifecycle more robust to prevent errors. These changes improve server flexibility and stability.

• I modified packages/komodo_mcp_server/bin/komodo_mcp_server.dart to allow disabling the stdio transport via a new --stdio command-line argument, providing more control over server startup behavior.
• In packages/komodo_mcp_server/bin/komodo_mcp_server.dart, I updated the wallet.get_public_keys tool call handler to return a JSON array of objects, each containing asset and keys, instead of a single map. This provides a more structured and iterable API response.
• I refactored the dispose() method in packages/komodo_mcp_server/lib/app.dart to ensure asynchronous resource cleanup and prevent setState calls on a disposed widget, enhancing application stability.
• I updated the executables entry in packages/komodo_mcp_server/pubspec.yaml to point directly to komodo_mcp_server, reflecting a change in how the executable is referenced or built.

I updated the pubspec.yaml configuration for the komodo_mcp_server package to correctly specify the main executable file. This ensures the server can be run directly using dart run or similar commands, improving project setup and execution.

• I modified the packages/komodo_mcp_server/pubspec.yaml file.
• I updated the executables entry for komodo_mcp_server to explicitly point to its Dart entry file, changing it from komodo_mcp_server to bin/komodo_mcp_server.dart. This aligns with standard Dart project structure for executables.

@cursoragent please review and make any necessary fixes

[cursor]

I refactored the komodo_mcp_server package by removing an unused dependency and updating an asynchronous call to ensure proper resource management. These changes streamline the codebase and improve the reliability of the application's lifecycle management.

• I removed the import 'package:decimal/decimal.dart'; statement from packages/komodo_mcp_server/bin/komodo_mcp_server.dart, as the Decimal package was no longer directly utilized in this entry point.
• I modified packages/komodo_mcp_server/lib/app.dart to await _sdk?.dispose(); within the _KomodoMcpAppState class. This ensures that the asynchronous dispose() method of the KomodoDefiSdk instance completes before further operations, preventing potential resource leaks or race conditions during SDK reinitialization.
