Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces the capability to perform local vulnerability scans using Python callables as agents. It integrates a new polling mechanism that allows the SDK to communicate with the Hub for agent invocations, enabling a seamless local development and testing workflow for agents. The changes enhance the HelpersResource by providing a unified scan interface for both remote and locally defined agents, abstracting the underlying communication and execution details.

Highlights

• Local Scan Functionality: Introduced a new scan method within the HelpersResource to support both remote and local agent vulnerability scans. This allows users to provide a Python callable as an agent for local execution.
• Polling Mechanism for Local Agents: Added a dedicated _poll_scan.py module containing run_poll_scan and arun_poll_scan functions. These functions handle the continuous polling for agent invocation requests from the Hub and submitting responses for local agents.
• Scan Orchestration: Implemented private helper methods, _scan_remote and _scan_local (with both synchronous and asynchronous versions), to manage the creation and execution flow for different types of agent scans.
• Utility for Local Scan Body Construction: A new build_local_scan_body function was added to _helpers_types.py to streamline the creation of the request body for local scan initiation.

Code Review

This pull request introduces a significant new feature: local scanning. It allows users to run vulnerability scans on local Python callables, which is a great addition. The implementation involves a new scan method in the helpers, which orchestrates the scan with the Hub and uses a polling mechanism to execute the local agent. The code is well-structured. I've added a few suggestions to improve logging for better debuggability and to simplify a piece of logic for better readability.
