  Problem 1
    - laravel/framework is locked to version v12.19.3 and an update of this package was not requested.
    - laravel/framework v12.19.3 requires league/commonmark ^2.7 -> satisfiable by league/commonmark[2.7.0].
    - league/commonmark 2.7.0 requires league/config ^1.1.1 -> satisfiable by league/config[v1.2.0].
    - league/config v1.2.0 requires nette/schema ^1.2 -> satisfiable by nette/schema[v1.3.2].
    - nette/schema v1.3.2 requires php 8.1 - 8.4 -> your php version (8.5.9) does not satisfy that requirement.
