v0.1.1 — Laravel 13 requirement fix
Corrects the framework constraint to Laravel 13 (illuminate/* ^13.0). The ^12 claim in v0.1.0 was not installable: brick/money ^0.14 requires brick/math >=0.15 (RoundingMode enum) while Laravel 12 caps brick/math at ^0.14. No API changes. CI now runs the PHP 8.4/8.5 x Laravel 13 matrix.
