When converting `types.Content` with a `function_response` to LiteLLM's `ChatCompletionToolMessage`, if the response is already a string, use it directly. Otherwise, serialize the response to JSON. This prevents double-serialization of string payloads

This change introduces `Gemma3Ollama`, a new LLM model class for running Gemma 3 models locally via Ollama, leveraging LiteLLM. The function calling logic previously in the `Gemma` class has been refactored into a `GemmaFunctionCallingMixin` and is now used by both `Gemma` and `Gemma3Ollama`. A new sample application, `hello_world_gemma3_ollama`, is added to demonstrate using `Gemma3Ollama` with an agent. Unit tests for `Gemma3Ollama` are also included.

This change expands the supported file MIME types and introduces provider-specific handling for file uploads. For providers like OpenAI and Azure, inline file data is now uploaded via `litellm.acreate_file` to obtain a `file_id`, which is then used in the message content. Other providers continue to use base64 encoded file data. Affected functions have been updated to be asynchronous

The RemoteA2aAgent now extracts a "task_id" from the custom metadata of the last agent event in the session, alongside the existing "context_id". This task_id is then included in the A2AMessage sent to the remote A2A service.

### Link to Issue or Description of Change
**1. Link to an existing issue (if applicable):**
- Closes: #3582
**2. Or, if no issue exists, describe the change:**
_If applicable, please follow the issue templates to provide as much detail as
possible._
**Problem:**
Currently, the BigQuery tool in ADK does not provide a way for developers to add custom labels to BigQuery jobs created by their agents. This makes it difficult to:
Track and monitor BigQuery costs associated with specific agents or use cases
Organize and filter BigQuery jobs in the Google Cloud Console
Implement billing attribution and resource organization strategies
Differentiate between jobs from different environments (dev, staging, production)
While the tool automatically adds an internal adk-bigquery-tool label with the caller_id, there's no mechanism for users to add their own custom labels for tracking and monitoring purposes.
**Solution:**
Add a labels configuration field to BigQueryToolConfig that allows users to specify custom key-value pairs to be applied to all BigQuery jobs executed by the agent. The solution should:
Configuration Option: Add an optional labels parameter to BigQueryToolConfig accepting a dictionary of string key-value pairs
Validation: Ensure labels follow BigQuery's requirements (non-empty string keys, string values)
Job Application: Automatically apply configured labels to all BigQuery jobs alongside the existing internal labels Documentation: Provide clear documentation on how to use labels for tracking and monitoring

The Gemini API may not always send an explicit transcription finished signal. This change ensures that any buffered input or output transcription text is yielded as a finished transcription when a turn is completed, generation is complete, or the session is interrupted.
Also, refined the check for `event.partial` in runners.py to be more explicit.

LlmAgentConfig.model now accepts either a plain model string or a CodeConfig. This lets YAML configs pass a LiteLLM instance with managed API settings (e.g., api_base and fallbacks) so agents can hit KimiK2’s managed endpoint instead of only the default modelID.

This change adds new `POST` endpoint `/apps/{app_name}/users/{user_id}/sessions/{session_id}/artifacts` to the ADK web server. This endpoint lets clients to save new artifacts associated with a specific session. The endpoint uses `SaveArtifactRequest` and returns `SaveArtifactResponse`, including the version and canonical URI of the saved artifact.

Default CLI session storage to SQLite instead of in-memory
Previously, adk run and adk web used in-memory session storage by default, causing sessions to be lost on restart. Now sessions persist to .adk/session.db automatically. To use in-memory storage, pass --session-service-uri memory://

Previously, image parts were always filtered out when converting content to Anthropic message parameters. This change updates the logic to only filter out image parts and log a warning when the content role is not "user". This enables sending image data as part of user prompts to Claude models
