v0.17.4

Features

• Async file extraction: Converted file processing to be fully asynchronous to prevent blocking the main thread.
  • Added FileHandler.async_process_file() to offload blocking I/O to a thread pool.
  • Updated CodeAnalysisService.get_file_content(), MCP resource formatting, A2A adapter, and ACP filesystem handler to use async variants.
• GitHub Copilot service – Simplified tool message handling and removed model‑specific workarounds (e.g., special handling for gpt‑4.1).

Chores & Cleanup

• Removed deprecated fallback code paths in AgentCrew.app, a2a/task_manager.py, file_commands.py, and github_copilot_service.py that were never executed.
