🐛 Patch Changes

• 483d6c1: Close object schemas in Anthropic structured output. Every type: object node in output_config.format.schema now gets additionalProperties: false (unless the author set it), on both the chat-completions → Anthropic translation and the native /v1/messages pass-through, so Anthropic no longer rejects requests with "For 'object' type, 'additionalProperties' must be explicitly set to false".
• 8f4fd02: Fix Kiro agent loops. When a request ends on a tool result with no new user text, leave the current Kiro turn empty instead of synthesizing continue (or leaving the system prompt there). Kiro read that fabricated text as a fresh instruction and dropped the in-flight task, so tool-calling agents (opencode et al.) lost context immediately after the first tool call. The system prompt now rides the conversation's first user turn so it still reaches the model.
