fix: debug wait for terminate

[cristipufu]

Description

This PR refactors the debug bridge to use an asyncio Event for termination signaling instead of a boolean flag, and updates the uipath-runtime dependency from 0.0.21 to 0.1.0

• Replaced _quit_requested boolean flag with _terminate_event asyncio Event for better async coordination
• Added new wait_for_terminate() method to enable waiting for termination signals
• Updated version to 0.0.8 and bumped uipath-runtime dependency to 0.1.0

Ref: UiPath/uipath-runtime-python#36
