Pull request overview

This PR introduces a dedicated CodeQL configuration file and simplifies the existing CodeQL GitHub Actions workflow by moving inline configuration into that file and removing now-unneeded build/setup steps.

Changes:

• Added a repository-level CodeQL.yml config that centralizes paths-ignore patterns.
• Updated the CodeQL workflow to reference the config via config-file and simplified the C# job to build-mode: none.
• Added a workflow_dispatch trigger to allow manual runs.

• The matrix.include list items are indented at the same level as include: (instead of being nested beneath it). This makes the workflow invalid YAML and will prevent the CodeQL job from running.

      matrix:
        include:
          - language: actions
            build-mode: none
          - language: csharp
