This pull request includes several updates to the GitHub Actions workflows to improve test code coverage and indicators. The changes involve modifying the workflow triggers, adding concurrency limits, updating environment variables, and refining the job matrix configurations.

Key changes include:

Workflow Trigger and Concurrency:

• .github/workflows/test-code-coverage.yml: Changed the trigger from pull_request to pull_request_target and added concurrency limits to prevent multiple runs from overlapping.

Environment Variables and Checkout:

• .github/workflows/test-code-coverage.yml: Added the CODACY_PROJECT_TOKEN environment variable and updated the checkout step to explicitly reference the pull request code.

Python Version Update:

• .github/workflows/test-code-coverage.yml: Updated the Python version from 3.12 to 3.13 for the Setup Python step.

Job Matrix Configuration:

• .github/workflows/test-indicators.yml: Refined the job matrix to include specific OS, .NET, and Python version combinations, and added a post-summary flag for certain configurations.

Conditional Steps and Error Handling:

• .github/workflows/test-indicators.yml: Updated conditions for steps based on the new post-summary flag and added continue-on-error: true for the Test indicators step. [1] [2]
