Update CI matrix and GitHub Actions versions

Refresh CI configuration and workflows to use current runners and action releases. .github/matrix.json: simplify job names, replace explicit OS versions with ubuntu-latest/macos-latest/windows-latest and remove per-job compiler "version" fields. .github/workflows: bump actions/checkout to v6, ssciwr/doxygen-install to v2, and actions/upload-pages-artifact to v4; set CC/CXX without toolchain-version suffix to rely on runner defaults. These updates keep CI up-to-date and simplify compiler/environment setup across the matrix.
