TYPO3 Core

When developing your extension, the import of your Initialisation/Files is not working because the path handling wont support the directory structure.

The "typical" setup will be the following:
It can be seen in many many extensions and is documented here:
https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/Testing/ExtensionTesting.html

What exactly do you consider "typical" and what do you think from that is documented?

        "post-autoload-dump": [
            "cd .Build/vendor && mkdir -p my_vendor && rm -f my_vendor/my_package && ln -s ../../.. my_vendor/my_package && cd -; fi",
            "mkdir -p .Build/config/system && cd .Build/config/system && ln -sf ../../../Resources/Private/Build/additional.php && cd -; fi" 
        ]

Linking the extension into the vendor folder is non functional. It does not do anything and therefore should rather be removed (it also has a syntax error).

Linking the configuration might be useful, but is non functional with TYPO3 12, as the config folder always is top level.

        "typo3/cms": {
            "cms-package-dir": "${vendor-dir}/typo3/cms" 
        }

This does not do any more since the subtree split (TYPO3 8.7) and can safely be removed.

    "config": {
        "vendor-dir": ".Build/vendor",
        "bin-dir": ".Build/bin" 
    },

       "typo3/cms": {
            "web-dir": ".Build/Web" 
    }

These should be fine, if one prefers it like that, but latest with TYPO3 12, I would rather recommend going with the defaults

    "minimum-stability": "dev",
    "prefer-stable": true,

Such configuration is not required and should rather be removed.

   "require": {
        "php": "^8.2",
        "ext-SimpleXML": "*",
        "ext-json": "*",
        "typo3/minimal": "^12.4" 
    },

All package names should/ must be lower case.
An extension requiring typo3/minimal is highly discouraged and likely counter productive.
Please add the TYPO3 packages as requirement, that your extension really depends on.

Once you change these, what code exactly does fail for you? Please provide reproducible examples of what you are trying to achieve, what your expectations are and what the actual result is.
