refactor: pass company ID in WebSocket code analysis requests

[firedragon9511]

Summary

• Read the Company ID from the Visual Studio extension settings.
• Send company_id as a numeric value in every analyze_code payload.
• Include the Company ID in regular code analysis and autofix requests.
• Validate that the configured Company ID is numeric before sending and return a clear error when it is missing or invalid.
• Require an authenticated WebSocket connection before sending broker requests.
• Detect authentication failures and trigger reconnection on the next operation.
• Increase the extension version from 0.2.2 to 0.2.3.

New websocket analyze_code request format:

{
    "type": "analyze_code",
    "request_id": "...",
    "payload": {
      "code": "...",
      "language": "...",
      "company_id" : "..."
    }
  }

Change type:

• Feature
• Fix
• Refactor
• Docs
• Chore

Checklist

• Built the Visual Studio extension with MSBuild.
• Confirmed company_id is serialized as a JSON number.
• Updated both code analysis and autofix request payloads.
• Updated README if behavior changed.
• Confirmed the generated VSIX builds successfully.
• Confirmed protocol alignment with ide-broker.****
