fix: replace retired claude-3-5-haiku-20241022 with claude-haiku-4-5#1719
Merged
Conversation
Closes kagent-dev#1695. claude-3-5-haiku-20241022 returns a 404 from the Anthropic API so a fresh install with the anthropic provider fails at chat time with no indication during install. Updated the default model in values.yaml and the matching helm unit test to claude-haiku-4-5. Also updated the AnthropicVertexAI model list in the models handler to the equivalent Vertex AI model ID.
