Bug Fixes

• Copilot Long Responses: Copilot on Opus now uses its full 128K output limit, so large Node creation no longer gets cut off mid-response.

• Copilot Tool Cards: Tool cards resolve when a response ends instead of spinning forever, and truncated responses are called out in chat.

• Copilot Conversation Recovery: A failed tool call no longer breaks the rest of the conversation, and a failed Node creation cleans up after itself instead of leaving an empty Node behind.

• Databricks OAuth on Azure: OAuth M2M connections to commercial Azure Databricks workspaces authenticate correctly. (Shipped in 7.39.3.)
