Migration to v0.5

Assistant Message Status / Content Part Status

The previous AssistantMessage.status field has been reworked:

• in_progress is now { type: "running" }
• error is now { type: "incomplete", reason: "error", error: unknown }

The previous value done now maps to one of the following values:

• { type: "requires-action", reason: "tool-calls" }
• { type: "complete", reason: "stop" | "unknown" }
• { type: "incomplete", reason: "cancelled" | "tool-calls" | "length" | "content-filter" | "other" }

The same applies to ContentPart status fields.
