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

Optional Bundle architecture: Schedule (session-local delayed / timed / interval reminders) was removed from the default set and made an explicit Optional Bundle. This cleanly separates “installed” from “enabled” and is the first systematic use of the Profile + Bundle model for official features.

• Windows Sandbox improvements: A new permission-diagnosis skill can detect common Access Denied causes and perform backed-up, recoverable permission fixes after user authorization, giving the Agent a reliable recovery path instead of blind retries.

• Async Question Mode (experimental): “Ask the user” is no longer a hard synchronous block. After a timeout the Agent can keep working while the user answers later, introducing asynchrony between interaction and execution.

• Model-layer polish: DeepSeek-account sessions can use Web Search without an extra API key; third-party model catalog updated (some old IDs removed); long model lists now support fuzzy search and keyboard navigation.

• Desktop release: Official Windows and macOS clients are out (Linux unsupported). Account login is supported, suggesting paid plans may be coming soon.

• Overall theme: Version 0.2 strengthens the Agent Runtime’s composability, recoverability, permission boundaries, and execution-state semantics — the practical foundations needed to move from a toy toward production use.
