Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires codeigniter/phpstan-codeigniter ^1.5.1 -> satisfiable by codeigniter/phpstan-codeigniter[v1.5.1]. - codeigniter/phpstan-codeigniter v1.5.1 requires codeigniter4/framework ^4.5 -> found codeigniter4/framework[v4.5.0, ..., v4.5.7] but these were not loaded, likely because it conflicts with another require.
