## What changed - Propagate MCP tool `readOnlyHint` annotations through tool-call start and completion events. - Include the optional hint in persisted thread history and app-server `mcpToolCall` items, preserving compatibility when the annotation is absent. - Document that the hint describes tool capability, not the outcome of a particular invocation. ## Testing - Cover read-only and write-capable tools in live events and persisted rollout data. - Verify the hint survives thread reads and resumes for both in-progress and completed MCP calls.
