Two tools - detect_anomalies and analyze_contribution are modifying the settings passed to them, which is not right as the settings are held and passed by the top level, which means several tools share the same settings.

This is ~27% of the current cold start latency after previous changes are submitted. This change refactors `google.adk.tools/__init__.py` to use `__getattr__` for lazy loading of all tools and related classes. Previously, all modules were imported directly upon `google.adk.tools` import, leading to potentially long initial import times. With lazy loading, modules are only imported when they are first accessed, improving the initial startup performance.

This change:
* Deprecates the `save_live_audio` configuration option in `RunConfig`, introducing `save_live_blob` as its replacement. A warning is issued if `save_live_audio` is used.
* Updates `base_llm_flow.py` to use the new `save_live_blob` flag.
* Ensures that audio events generated by `audio_cache_manager.py` are properly appended to the session service.
* Adds a utility script `pcm_audio_player.py` for playing raw PCM audio files.

The change adds an extension point for controlling which request metadata gets attached to A2A requests made by a RemoteAgent.
Instead of taking metadata from custom_metadata of session events users can construct payloads using a2a_request_meta_provider.
request_meta feature was added in v0.3.11 of the a2a-sdk library: https://github.com/a2aproject/a2a-python/releases/tag/v0.3.11

This is targeting the Client import mostly, but also prevents future latency increase if the other modules in genai adds more 3p dependencies. This change will make ADK only import `live`, `Client` and `_transformers` just-in-time, therefore cutting down cold start latency.

This update improves the `BigQueryAgentAnalyticsPlugin` in several ways:
* Corrects the PyArrow schema generation to accurately reflect BigQuery field nullability based on the `mode` attribute.
* Introduces a configurable `shutdown_timeout` in `BigQueryLoggerConfig` to manage how long the plugin waits for pending logs to flush during shutdown.
* Adds more robust error handling within the `shutdown` method and background write tasks, particularly for event loop closure issues.
* Improves internal logging to provide better diagnostics.
* Ensures consistent use of safe content formatting.

This change introduces a mechanism for users to register their own custom backend services for sessions, memory, and artifacts without modifying the ADK framework. This enhances the extensibility of ADK.
Two methods of registration are supported, both by placing a file in the parent directory of the agents.
**YAML Configuration (services.yaml or .yml)**
This is the recommended approach for simple services that can be instantiated with a constructor like MyService(uri="...", **kwargs).
Example services.yaml:
```
services:
- scheme: mysession
type: session
class: my_package.my_module.MyCustomSessionService
```
**Python Registration (services.py)**
For services requiring more complex initialization logic, users can define factory functions in a services.py file.
Example services.py
```
from google.adk.cli.service_registry import get_service_registry
from my_package.my_module import MyCustomSessionService
def my_session_factory(uri: str, **kwargs):
# custom initialization logic
return MyCustomSessionService(...)
get_service_registry().register_session_service("mysession", my_session_factory)
```
ADK will load services from services.yaml/.yml first, and then from services.py. If the same service scheme is defined in both, the registration in services.py will take precedence.
To use a registered service, specify its URI via the corresponding command-line flag, e.g., `--session_service_uri=mysession://....`

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.

The `google.cloud.storage` module is now imported within the `__init__` method of `GCSArtifactService`, rather than at the top level. This avoids importing the potentially heavy `storage` module unless an instance of `GCSArtifactService` is actually created.
