## Description
This PR fixes false positive stale labels in the `adk_stale_agent`.
Previously, the agent was incorrectly identifying the issue as "stale" because it treated `adk-bot` (acting via PAT) as a human maintainer. Since the username lacks the `[bot]` suffix, administrative alerts (e.g., "Notification: The author has updated...") were counted as maintainer activity, inadvertently triggering the stale logic immediately after an author's edit.
## Changes Made
- **Hardcoded Bot Exclusion:** Added `BOT_NAME = "adk-bot"` and updated history parsing loops (comments, edits, timeline) to explicitly ignore this actor.
- **Bot Alert Skip:** Added logic to `continue` (skip) processing the bot's specific "Notification" comment so it is not recorded as the last activity on the timeline.

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.

LiteLLM's `ollama_chat` provider does not accept array-based content in messages. This change flattens multipart content by joining text parts or JSON-serializing non-text parts before sending the request to the LiteLLM completion API. This ensures compatibility with Ollama's chat endpoint.

# Problem
The example in `contributing/samples/human_in_loop/README.md` shows:
```python
await runner.run_async(...)
```
However, `run_async` returns an **async generator**, so awaiting it raises:
```
TypeError: object async_generator can't be used in 'await' expression
```
Additionally, the example payload uses `"ticket-id"` while ADK tools and other examples use `"ticketId"`, creating a mismatch that breaks copy/paste usage.
# Solution
- Updated the snippet to consume the async generator correctly:
```python
async for event in runner.run_async(...):
...
```
- Aligned the payload key from `"ticket-id"` → `"ticketId"` for consistency with ADK schema and other examples.
These changes make the example runnable and consistent with the API’s actual behavior.
# Testing Plan
This PR is a **small documentation correction**, so no unit tests are required per contribution guidelines.
- Verified the corrected snippet manually to ensure it no longer raises `TypeError`.

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.
