DeepSeek harness 0.2 - Optional Bundle Architecture, Windows Sandbox improvements, Async Question Mode, Desktop release, Web Search without key

DeepSeek harness 0.2 introduces an Optional Bundle architecture, exemplified by moving the Schedule feature out of the default set. This release enhances the Agent Runtime's composability and recoverability, laying practical foundations for production use. Key improvements include Web Search without an API key for DeepSeek-account sessions, an updated third-party model catalog with fuzzy search, and Windows Sandbox improvements. The update also features Async Question Mode and a Desktop release, strengthening the system's overall robustness and user experience.

This release marks the first systematic use of the Profile + Bundle model for official features, unlike earlier versions where Schedule was part of the default set.
