There isn't a consistent format for MCP server urls in the registry-- some customers add the https:// but others don't. To standardize, only prepend if it isn't there already.

This gcloud authentication header is required as a project override when using google ADC credentials. It is required for all OneMCP servers. Originally I manually put it in the big query sample, but since it is used for all OneMCP, it makes sense to just add it to the core API Registry logic. I also refactored the auth header logic a bit to deduplicate.

This calls the cloudapiregistry.googleapis.com API to get MCP tools from the project's registry, and adds them to ADK.

Retrying only on closed_resource error is not enough to be reliable for production environments due to the other network errors that may occur -- remote protocol error, read timeout, etc. We will update this to retry on all errors. Since it is only a one-time retry, it should not affect latency significantly. Fixes https://github.com/google/adk-python/issues/2561.

Currently logic to check for a disconnected session only checks for certain headers but doesn't detect all cases, leading to situations where it tries to connect to a session that is down. This adds logic so that we ping the server to check if it is disconnected. Fixes https://github.com/google/adk-python/issues/3321.

Users were getting spammed with this log even though their tools didn't require authentication. To fix, reduce the log level to DEBUG so that it doesn't show up by default.

While testing the bidi streaming sample agent, I noticed that the import was erroring and I think it's a typo -- the other bidi sample agents all import `from google.adk.agents.llm_agent`.

Since it appears in the same bubble as the rest of the LLM's response text, make it more human readable so it doesn't look out of place.

Previously BuiltInCodeExecutor was missing the logic to save output files from executed code as artifacts, so images/visualizations wouldn't show up in the UI. This fix will iterate through all parts of the LlmResponse, and if any of them are images, it will save the image data using artifact_service (similar to what is done in VertexAICodeExecutor).
This fixes the backend, but there are still UI bugs that should be fixed -- events without content are currently ignored, so the image doesn't appear even though it is saved. We will add the UI fix in a separate change.
