Implement Real-Time SSH Command Output Streaming

[zjasper666]

Overview

Currently, the SSH command execution waits for the entire command to complete before returning the output. This can be problematic for long-running commands or when real-time feedback is needed. We need to implement streaming output functionality for remote SSH command execution.

Current Implementation

The current implementation in SSHManager.execute():

• Uses Paramiko's exec_command()
• Waits for command completion
• Returns complete output as a single string
• No progress visibility during execution

Proposed Changes

1. Core SSH Manager Updates

   • Modify execute() to support streaming mode
   • Implement generator-based output streaming
   • Add buffer size configuration
   • Handle both stdout and stderr streams

2. API Changes

   • Add streaming parameter to RemoteShellInput
   • Update return type to support both string and generator modes
   • Implement progress callbacks
   • Add timeout configuration

3. UI/UX Improvements

   • Real-time output display in terminal
   • Progress indication for long-running commands
   • Color-coded output (stdout vs stderr)
   • Support for command interruption

4. Langchain Integration

   • Update HyperbolicTool to support streaming outputs
   • Implement Langchain streaming callbacks
   • Integrate with Langchain's streaming interfaces
   • Support async execution in Langchain agent
   • Add streaming support to HyperbolicAgentkitWrapper

Success Criteria

• Real-time output streaming for remote commands
• Minimal latency between command execution and output display
• Proper error handling and status reporting
• Backward compatibility with existing code
• Documentation for new streaming features

Testing Requirements

1. Unit Tests

   • Test streaming functionality
   • Verify error handling
   • Check timeout behavior
   • Test large output handling

2. Integration Tests

   • Test with various command types
   • Verify real-world performance
   • Test interruption handling
