Enhance and Clean Up by AI Agents

Here are the release notes for version 1.2.3 of the corr-solver-cpp project, which includes several maintenance updates and compatibility improvements.

Release Highlights

• Version Update: The project has been updated from version 1.2.2 to 1.2.3.
• Stability & Compatibility: The release focuses on fixing regressions, updating dependencies, and improving cross-platform reliability.

What's Changed

🧹 Code & Package Maintenance

• Formatting & Documentation: Various formatting, documentation, and packaging updates were applied to keep the project tidy.
• Style Updates: The code style was refined to improve consistency.
• Workflow Cleanup: Obsolete GitHub Actions workflows, such as the style.yml job, have been removed, and others have been updated for efficiency.

🐛 Bug Fixes & Regression Resolution

• Several regressions were fixed to improve the solver's correctness and stability.

⚙️ Dependency & Build System Updates

• Dependency Upgrades: The PackageProject.cmake dependency was updated to version 1.8.0.
• EllAlgo Rollback: The EllAlgo dependency was temporarily rolled back to version 1.4.8 to address compatibility issues.
• EllAlgo Update: Later, the EllAlgo dependency was updated to version 1.5.1, which includes a change from Q.p to Q.pos.
• OpenBLAS: OpenBLAS remains a required dependency for linear algebra operations, as mentioned in the project's documentation.

🛠️ Cross-Platform & Compiler Compatibility

• MSVC: Compiler warnings (C4267, C4244) originating from xtensor headers are now suppressed.
• Clang/GCC: Sign conversion warnings are suppressed with -Wno-sign-conversion to match the behavior of MSVC.
• macOS: The XTENSOR_DISABLE_SVECTOR macro is now defined on Apple platforms to avoid Clang template ambiguity issues.

🚧 Configuration & File Cleanup

• Removed development configuration files that are no longer needed, including:
  • .clang-tidy-bak
  • .flake8
  • .isort.cfg
  • .markdownlint.yaml

⚠️ Upgrading Notes

• The project now requires CMake 3.5 or later, as enforced by the -DCMAKE_POLICY_VERSION_MINIMUM="3.5" flag in the Windows workflow.
• If you are building on macOS, be aware that svector support is now disabled by default to prevent template errors.
• The EllAlgo dependency has seen a version change; please ensure your environment is compatible with version 1.5.1.
