refactor: improve file-io errors

[ComradeVanti]

Refactor logic for file-system related io errors. The main changes are:

• We now log all file-system errors when they happen using the debug logger. This way we don't need to bubble the errors all the way up to the cli layer.
• There are now two file-system error types as part of the domain. One for when a file is missing and one for everything else.
• The FileMissingError allows to pass a constant string which identifies the missing file ("ProjectVersion.txt", "ProjectManifest", ...). This way the error can be reused for different files but still be differentiated for better logging.
