This seems a breaking change, but actually credential manager is used internally only and also it won't work if some one call it using callback context

The ADK web server's /run_sse endpoint now yields a JSON object like {"error": "..."} when an exception occurs during event generation. The adk_web_server_client is updated to detect this error payload and raise a RuntimeError.

The `_part_has_payload` helper now returns False for parts containing a function response, preventing the addition of fallback user content when a user turn consists solely of tool outputs.

For providers that typically require file IDs (like OpenAI and Azure), if a file URI is an HTTP/HTTPS URL and the MIME type is image, video, or audio, convert it to the corresponding URL-based content type (e.g., "image_url") instead of using the generic "file" type

This change introduces a new function, _validate_agent_import, which attempts to import the user's agent.py file before the deployment process begins. This helps catch common issues such as missing dependencies, incorrect relative imports, or syntax errors in the agent code early, providing more informative error messages to the user.

This CL enhances asyncio event loop management and test isolation.
- **BigQuery Analytics Plugin:** Ensure the asyncio event loop is consistently closed within the BigQuery analytics plugin. This prevents potential resource leaks. Add checks to handle potential deadlocks in Python 3.13+ when creating loops during interpreter shutdown.
- **Test Thread Pool Cleanup:** Introduce a pytest fixture (`cleanup_thread_pools`) to automatically shut down and clear all tool-related thread pools after each test run in `test_functions_thread_pool.py`. This improves test isolation and prevents order-dependent test failures.
- **Streaming Test Loop Restoration:** Refactor event loop handling in `test_streaming.py`. A new `_run_with_loop` method is introduced in the custom test runners to create a temporary event loop for each test execution, run the coroutine, and crucially, restore the original event loop afterwards. This prevents tests from interfering with each other's loop state.
- **Resource Closure:** Ensure services are closed properly in tests by adding `await service.close()` in `test_service_factory.py` and using `async with session_service` in `test_session_service.py`.

Improves test reliability by guaranteeing the BigQueryAgentAnalyticsPlugin is shut down after each test execution. This is achieved by wrapping test logic in try/finally blocks, using a yield fixture, or employing a new asynccontextmanager to ensure the plugin.shutdown() method is always called, preventing potential resource leaks between tests.

Since we will save MCP resource contents to the artifact service, no need to do post-processing based on mime type. Also fixed the implementation; the correct method to call is session.read_resource(uri).

Merge https://github.com/google/adk-python/pull/4276
This adds 2 mypy GitHub Actions checks:
* `mypy.yml` runs mypy on every PR. This will list all errors, so it shouldn't block until errors are resolved.
* `mypy-new-errors.yml` compares the PR branch to `main` to ensure no new mypy errors are introduced. This check can be made blocking now and can be removed once all errors are resolved in favor of `mypy.yml`.

This allows users to access MCP resources on their own within agent logic / using custom tools. I plan on also later adding it to the agent state.

* The main fix is in eval_metrics.py
* Removed some deprecated paths in the FastAPI server
* Added a unit test to catch future breakages
* Bump fastapi version to be 0.124.1 to capture the fix in https://github.com/fastapi/fastapi/pull/14482
* Removed the upper-bound restriction on fastapi version which was used to temporarily fix the issue
Fixes#3173

Details:
* The Sampler allows ADK agent optimizers to request evals and receive detailed eval results that can be used to guide agent optimization.
* This interface allows developers to run custom evaluations if needed for their agent. An implementation to interface with the inbuilt LocalEvalService shall be published shortly in a follow-up PR.
* The AgentOptimizer interface describes the general framework for an ADK agent optimizer that uses the Sampler interface to optimize an ADK agent.
* data_types.py contains generic types and base classes to allow intercommunication between the AgentOptimizer, Sampler, and developer code.

This changes the behavior of how we handle stale session, instead of reject the transaction entirely, we aggresively refresh the session.
Removed synchronous inspect(self).session calls within StorageSession.update_timestamp_tz and _dialect_name. This introspection was causing deadlocks/hangs when used with sqlalchemy.ext.asyncio in Python 3.13.
