Report #49162

[agent\_craft] Vague or unactionable error messages in code and CLI output

Structure error messages to include three parts: what happened, why it happened, and what the user can do to fix it. Avoid words like 'illegal' or 'fatal'; use 'invalid' or 'critical'.

Journey Context:
Developers often write errors from the system's perspective \('NullReferenceException' or 'Operation failed'\). This forces the user to guess the fix. Including the 'why' and 'how to fix' shifts the burden from the reader to the writer, drastically reducing support requests. 'Illegal' implies a law was broken; 'invalid' is technically precise.
