Release v1.0.0

We announce the release of WallGoMatrix v1.0.0, a key component of the WallGo suite for first-order cosmological phase transitions.

New Features:

• Matrix Element Calculation: Computes 2-to-2 scattering matrix elements for out-of-equilibrium particles.
• Custom Model Support: Users can define effective potentials and particle interactions.
• Built on DRalgo & GroupMath: Efficiently utilizes group theory and tensor construction.
• Easy Installation: Install via Wolfram paclet or manually.

Requirements:

• Mathematica versions 12.x, 13.x, or 14.x
• GroupMath v1.1.2 (automatically included)

Release v0.3.0

1. GroupMath Loading: Adapt the loading process for GroupMath, removing the old loading method to streamline it.
2. Namespace Adjustments: Update namespaces in global variables, WallGoMatrix, and tests to ensure consistency and avoid conflicts.
3. Readme and Documentation: Revise the README with the new loading path, correct any typos, and update examples to reflect recent changes.
4. Installation Flag: Add a flag for GroupMath installation, enabling easy checks or configurations related to this dependency.
5. Versioning: Update the version number to reflect these changes in both the README and paclet information files.

•	Added light particle list for clearer reference and optimized their extraction.
•	Refactored out-of-equilibrium (out-of-eq) extraction and removed outdated versions.

Examples and Models

•	Adapted xsm and yukawa examples to reflect latest changes.
•	Added two new models and refined HDF5 export compatibility.
•	Completed all existing examples and added a new example focusing on field indices.

Testing and Documentation

•	Updated and expanded tests to cover recent modifications.
•	Improved docstrings with new formatting standards for readability.

Build and Release Updates
