Code Review

This pull request introduces the MaxKernel Agent Development Kit (ADK), which includes comprehensive modules for autonomous and human-in-the-loop (HITL) agents, search algorithms (such as beam search and parallel search), evaluation utilities, and benchmarking datasets. It features specialized subagents for kernel writing, autotuning, profiling, and testing, along with supporting tools, prompts, and server configurations. There are no review comments to address, and the implementation appears complete.
