v0.38.0

0.38.0

Features Added

• Renamed the Chat* type family to Agent* across roboto.ai.core: AgentSession, AgentMessage, AgentRole, AgentSessionStatus, AgentMessageStatus, AgentContentType, and their content types (AgentTextContent, AgentToolUseContent, AgentToolResultContent, AgentErrorContent). The previous Chat* names remain as aliases.
• Added ClientToolSpec model for declaring client-side tools.
• Added SubmitToolResultsRequest model for returning client-executed tool results.
• Added CLIENT_TOOL_TURN status to AgentSessionStatus, signaling that the session awaits client-side tool execution.
• Renamed chat_id to session_id in AgentSession, with chat_id retained as a backwards-compatible computed alias in API responses.

Internals

• Moved canonical type definitions from roboto.ai.chat to roboto.ai.core. The roboto.ai.chat module re-exports all types for backwards compatibility.
• Renamed the ChatEvent streaming event types to AgentEvent (AgentStartTextEvent, AgentTextDeltaEvent, AgentTextEndEvent, AgentToolUseEvent, AgentToolResultEvent). The previous Chat* event names remain as aliases.

Bugs Fixed

• RobotoClient HTTP retry now handles DNS resolution failures on all platforms, bare ConnectionResetError during response reads, and additional ConnectionError subclasses (ConnectionRefusedError, ConnectionAbortedError, BrokenPipeError) on idempotent requests.
