Pull request overview
Adds a Storybook/MSW mock implementation for the Agent Answer API so atomic-generated-answer can be demoed with agent-id, and refactors the story play functions to avoid query duplication when switching stories.
Changes:
- Added
MockAgentApiMSW handlers for/agents/:agentId/answerand/agents/:agentId/follow-upstreaming responses. - Introduced streaming mock event sequences for “head answer” vs “follow-up” behavior.
- Updated
atomic-generated-answerstories to include the new mock and to submit the query in a way that doesn’t duplicate text across story switches.
