Description

Resolves #343

This PR introduces WebSocketCopilotTarget, enabling sending prompts to Microsoft Copilot via WebSocket.
Implementation reference: powerpwn/copilot/copilot_connector/copilot_connector.py

Warning

It's a work-in-progress. Core functionality is implemented as of 9823509. Try websocket_copilot_simple_example.py to test.

Current limitations:

  • Authentication (Puppeteer-based approach from reference) is not yet implemented. One must manually copy the full WebSocket URL from the browser.
  • There are still quite a few TODOs in the code, some of which I plan to address in different PRs – like Puppeteer-based authentication or supporting more data types – to make them easier to work on and review.
  • Unit and possibly integration tests are still NOT implemented
  • Maybe other stuff I forgot about :))

Refactor WebSocket message parser to handle multiple frames per message
73b07d0 
- Rename _parse_message() to _parse_raw_message()
- Split on record separator (\x1e) and processes all frames, not just first
- Add FINAL_DATA_FRAME (type 3) enum value for completion signals
- Extract bot message parsing logic into lambda for reusability
- Fixes stop condition to handle FINAL_DATA_FRAME and remove flawed
  "is_user_input and PING" logic
