There isn't a consistent format for MCP server urls in the registry-- some customers add the https:// but others don't. To standardize, only prepend if it isn't there already.

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.

- Stripping whitespace from custom LLM provider and model names when checking for "ollama_chat".
- Enhancing `_flatten_ollama_content` to correctly handle content that is None, a string, a dictionary, or an iterable (like a tuple) of content blocks, not just lists. This aligns with LiteLLM's `OpenAIMessageContent` type being an `Iterable`.

## Summary
Upgrade GitHub Actions to their latest versions to ensure compatibility with Node 24, as Node 20 will reach end-of-life in April 2026.
## Changes
| Action | Old Version(s) | New Version | Release | Files |
|--------|---------------|-------------|---------|-------|
| `actions/checkout` | [`v5`](https://github.com/actions/checkout/releases/tag/v5) | [`v6`](https://github.com/actions/checkout/releases/tag/v6) | [Release](https://github.com/actions/checkout/releases/tag/v6) | analyze-releases-for-adk-docs-updates.yml, check-file-contents.yml, discussion_answering.yml, isort.yml, pr-triage.yml, pyink.yml, python-unit-tests.yml, stale-bot.yml, triage.yml, upload-adk-docs-to-vertex-ai-search.yml |
## Context
Per [GitHub's announcement](https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/), Node 20 is being deprecated and runners will begin using Node 24 by default starting March 4th, 2026.
### Why this matters
- **Node 20 EOL**: April 2026
- **Node 24 default**: March 4th, 2026
- **Action**: Update to latest action versions that support Node 24
### Security Note
Actions that were previously pinned to commit SHAs remain pinned to SHAs (updated to the latest release SHA) to maintain the security benefits of immutable references.
### Testing
These changes only affect CI/CD workflow configurations and should not impact application functionality. The workflows should be tested by running them on a branch before merging.

Previously, the warning check occurred after "plugins" could be populated from "app.plugins". This caused the deprecation warning to trigger incorrectly even when plugins were properly provided via the app argument. Moving the check ensures it only triggers when the deprecated plugins argument is explicitly used.
The change also enhanced the condition that would trigger the warning to cover the empty list case.

### Link to Issue or Description of Change
**1. Link to an existing issue (if applicable):**
n/a
**2. Or, if no issue exists, describe the change:**
**Problem:**
In the Community Repo section of README.md, there was a missing space between the markdown link `[adk-python-community repo](...)` and the word `that`, causing the text to render as `repo](...)that` instead of `repo](...) that`.
**Solution:**
Add a single space between the closing parenthesis of the markdown link and the word "that" to fix the typo.
### Testing Plan
**Unit Tests:**
This is a small documentation/typo fix. No code changes were made.
**Manual End-to-End (E2E) Tests:**
I verified that the markdown renders correctly with proper spacing between the link and following text.

Part 2 of https://github.com/google/adk-python/discussions/3605.
The DatabaseSessionService now checks for the usage of a V1 schema based on the "adk_internal_metadata" table. Table creation and subsequent operations use either the V0 or V1 SQLAlchemy models accordingly. New databases will default to V1.
Migration script and CLI command will be provided in the next change.
