Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires hammerstone/sidecar ^0.7.1 -> satisfiable by hammerstone/sidecar[v0.7.1]. - Root composer.json requires laravel/framework 13.* -> satisfiable by laravel/framework[13.0.x-dev (alias of dev-master), 13.x-dev]. - hammerstone/sidecar v0.7.1 requires illuminate/filesystem ^8|^9|^10|^11|^12.0 -> satisfiable by illuminate/filesystem[v8.0.0, ..., 8.x-dev, v9.0.0-beta.1, ..., 9.x-dev, v10.0.0, ..., 10.x-dev, v11.0.0, ..., 11.x-dev, v12.0.0, ..., 12.x-dev]. - illuminate/filesystem[v10.0.0, ..., 10.x-dev] require illuminate/contracts ^10.0 -> found illuminate/contracts[v10.0.0, ..., 10.x-dev] but it conflicts with your root composer.json require (^12.0 | ^13.0). - illuminate/filesystem[v11.0.0, ..., 11.x-dev] require illuminate/contracts ^11.0 -> found illuminate/contracts[v11.0.0, ..., 11.x-dev] but it conflicts with your root composer.json require (^12.0 | ^13.0). - illuminate/filesystem[v8.0.0, ..., v8.11.2] require php ^7.3 -> your php version (8.4.18) does not satisfy that requirement. - illuminate/filesystem[v8.12.0, ..., 8.x-dev] require illuminate/contracts ^8.0 -> found illuminate/contracts[v8.0.0, ..., 8.x-dev] but it conflicts with your root composer.json require (^12.0 | ^13.0). - illuminate/filesystem[v9.0.0-beta.1, ..., 9.x-dev] require illuminate/contracts ^9.0 -> found illuminate/contracts[v9.0.0-beta.1, ..., 9.x-dev] but it conflicts with your root composer.json require (^12.0 | ^13.0). - Only one of these can be installed: illuminate/filesystem[v8.0.0, ..., 8.x-dev, v9.0.0-beta.1, ..., 9.x-dev, v10.0.0, ..., 10.x-dev, v11.0.0, ..., 11.x-dev, v12.0.0, ..., 12.x-dev, 13.0.x-dev, 13.x-dev], laravel/framework[dev-master, 13.x-dev]. laravel/framework replaces illuminate/filesystem and thus cannot coexist with it. - laravel/framework 13.0.x-dev is an alias of laravel/framework dev-master and thus requires it to be installed too.
