## Problem
When performing authentication flows via `OAUTH2` or `OPEN_ID_CONNECT`, the native `OAuth2Token` response from identity providers, like Google OAuth, often includes an `id_token` alongside the `access_token` and `refresh_token`. [MCP Toolbox](https://googleapis.github.io/genai-toolbox/resources/authservices/google/) implements authentication through ID Tokens and [integrates with ADK](https://google.github.io/adk-docs/integrations/mcp-toolbox-for-databases/) to provide easy tools management for the end-users.
However, the ADK's `update_credential_with_tokens` utility explicitly drops the `id_token`, preventing agents and tools from verifying user identity or extracting OIDC claims securely. Furthermore, the `OAuth2Auth` model does not have a designated field for `id_token`.
## Solution
1. Added an `id_token: Optional[str] = None` field to the `OAuth2Auth` pydantic model in `auth_credential.py`.
2. Updated `update_credential_with_tokens` in `oauth2_credential_util.py` to correctly extract and map `tokens.get("id_token")` into the `OAuth2Auth` credential object.
3. Updated the relevant unit tests to ensure `id_token` is asserted and preserved during credential updates.
### Testing Plan
- I have added or updated unit tests for my change.
- All unit tests pass locally.

The list_skills method is not for model tool listing, but for giving the developer flexibility to load the skill name/description at runtime (from discussion in go/orcas-rfc-555)

This CL fixes several bugs in the BigQuery Agent Analytics plugin and refactors the internal data-passing pattern for better type safety and maintainability.
- **Stale Loop State Validation:** Use `loop.is_closed()` — a public, reliable API — to detect and clean up stale asyncio loop states in `_batch_processor_prop`, `_get_loop_state`, and `flush`. The previous approach used `asyncio.Queue._loop` which is `None` on Python 3.10+, causing the check to always treat states as stale.
- **Quota Project ID Fallback:** Remove the `or project_id` fallback when setting `quota_project_id` on `BigQueryWriteAsyncClient`. This fixes Workload Identity Federation flows where the federated identity lacks `serviceusage.services.use` on the quota project.
- **Kwargs Passthrough:** Pass `**kwargs` through to `_log_event` in all callbacks. Previously only model callbacks forwarded them, causing custom attributes (e.g. `customer_id`) to silently drop for agent, tool, run, and error events.
- **State Delta Logging:** Replace the dead `on_state_change_callback` (never invoked by the framework) with `on_event_callback`, which is already dispatched by the runner for every event. Remove duplicate `STATE_DELTA` logging from `after_tool_callback`.
- **EventData Dataclass:** Replace the `**kwargs`-as-data-bus pattern in `_log_event` with an explicit `EventData` dataclass. This makes the interface self-documenting, catches typos at construction time, and eliminates shared dict mutation across `_resolve_span_ids`, `_extract_latency`, and `_enrich_attributes`. All 12 callback call sites now construct typed `EventData` instances.
- **Multi-Subagent Tool Logging Tests:** Add `TestMultiSubagentToolLogging` (6 tests) verifying that tool events are correctly attributed to subagents in multi-turn, multi-agent scenarios. Total tests: 111 (up from 60).

When we added the session_lock_map, it resulted in pickling errors during Agent Engine deployment. To fix, we implemented custom getstate and setstate methods to exclude the lock map lock and session lock map from pickling. Closes https://github.com/google/adk-python/issues/4486.

meanwhile also centralize input-stream creation in registration
Move the LiveRequestQueue stream creation from _call_live
(function_tool.py) to the lazy registration block in
_process_function_live_helper (functions.py). This centralizes the
input_stream: LiveRequestQueue annotation check and stream creation
in one place, and ensures the stream is also recreated on
re-invocation after stop_streaming resets it to None.
_call_live now simply passes the existing .stream if set, without
needing to know about LiveRequestQueue at all.

Using one lock and checking for tables creation instead of schema version.
Closes issue #4445

Merge https://github.com/google/adk-python/pull/4185
**Description**
This PR resolves#4100 by making the `new_message` field optional in the `RunAgentRequest` model.
**The Problem:**
When attempting to resume an agent session via the FastAPI web server, the request would fail with a `422 Unprocessable Entity` if `new_message` was omitted. This prevented "resume-only" workflows where a user just wants to wake up an existing session.
**The Solution:**
Updated `RunAgentRequest.new_message` to be `Optional[types.Content] = None`. The underlying `runner.run_async` logic already supports `None` for resuming purposes, so no further logic changes were required.
**Verification:**
Verified that `RunAgentRequest` now validates successfully when `new_message` is missing, defaulting the field to `None`.
