ci(genai): Update genai directory to run tests in specific directories only

[holtskinner]

PRs for the Gen AI SDK have been blocked due to test timeout failures due to all of the tests in the full repo running for every PR. This adds dedicated testing directories to prevent this issue.

Follows similar pattern to functions/ directory

Summary of Changes

Hello @holtskinner, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request establishes a standalone continuous integration workflow for genai related tests. This strategic separation aims to enhance the efficiency of the testing process by ensuring that genai tests are only triggered when relevant files are altered, thereby improving test isolation and reducing unnecessary build times.

Highlights

• Dedicated CI Workflow for GenAI: A new, dedicated CI workflow has been created specifically for genai tests, moving them out of the shared custard-ci workflow.
• Improved Test Efficiency and Isolation: This change ensures that genai tests will only execute when files within the genai/ directory are modified, leading to more efficient test runs and better isolation of the testing environment.
• Configuration Update: The .github/config/nodejs.jsonc file has been updated to explicitly exclude the genai directory from the general Node.js CI configuration, as it now has its own dedicated workflow.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request aims to create a dedicated CI workflow for genai tests. While it correctly excludes the genai directory from the existing shared workflow in .github/config/nodejs.jsonc, it fails to include the new dedicated workflow file (.github/workflows/genai.yaml). As a result, merging this PR in its current state would disable all tests for the genai module. The missing workflow file must be added before this PR can be approved.
