IDEasy does not warn user if IDE_ROOT is not sane

[jan-vcapgemini]

Actual behavior

As an IDEasy user I expect that IDE_ROOT always gets used properly.
If I've installed my IDEasy to D:\projects and I'm running it using a different user.dir e.g. D:\Projects IDEasy will report some strange error messages:
Undefined edition null of tool intellij
as well as create faulty plugin marker files like: plugin.eclipse.null.checkstyle.

Comment JH: I would not consider this as a bug. If you use IDEasy properly there is no such problem. You are requesting better support for edge-cases here. Your reproducer instructions tell me to break the sane installation therefore, IMHO a robustness enhancement. However, might be a PoV if bug or feature. BTW: If you want to say that our detection of the edition is a hack, I would agree but for that create a new story since this is something completely different. I was always proposing to also create an .ide.software.edition file just like .ide.software.version file or to have both in a single file. However, this could not easily be done backward compatible.

Reproduce

1. Adjust your Windows Terminal Start directory to use your IDE_ROOT in uppercase (your actual IDE_ROOT needs to be in lower case)
   
2. Create a test project e.g. ide create test -
3. Switch to your test project e.g. icd -p test
4. Delete plugin marker files of intellij from $IDE_ROOT/test/.ide folder
5. Run ide -d intellij

Expected behavior

IDEasy should not report these messages and create proper plugin marker files.
IDeasy should warn the user if he uses a different CWD path than his IDE_ROOT.

Comments/Hints

This seems to be related to this method:

IDEasy/cli/src/main/java/com/devonfw/tools/ide/tool/LocalToolCommandlet.java

Lines 357 to 371 in f365719

	private String getEdition(Path toolRepoFolder, Path toolInstallFolder) {
	int toolRepoNameCount = toolRepoFolder.getNameCount();
	int toolInstallNameCount = toolInstallFolder.getNameCount();
	if (toolRepoNameCount < toolInstallNameCount) {
	// ensure toolInstallFolder starts with $IDE_ROOT/_ide/software/default/«tool»
	for (int i = 0; i < toolRepoNameCount; i++) {
	if (!toolRepoFolder.getName(i).toString().equals(toolInstallFolder.getName(i).toString())) {
	return null;
	}
	}
	return toolInstallFolder.getName(toolRepoNameCount).toString();
	}
	return null;
	}

which will return null if the path case did not match.
Also this line might have to be modified:

IDEasy/cli/src/main/java/com/devonfw/tools/ide/context/AbstractIdeContext.java

Lines 158 to 162 in f365719

	if (workingDirectory == null) {
	workingDirectory = Path.of(System.getProperty("user.dir"));
	} else {
	workingDirectory = workingDirectory.toAbsolutePath();
	}

The same issue will occur if the working directory was changed in intellij:
