Add Option to Disallow Any File and Pattern that Were Not In Allowlist (i.e. In MustHave Array)

Feature Description

Hello,

Let's say I'm using Konsistent to define what my project directory and subdirectory and files look like, after I do that using MustHave, I want to also make Konsistent warn or error anytime there's an folder or file existed that wasn't defined in my musthave array and definition.

This way Konsistent can prevent things to exist that developer is unaware of, or AI agent create a file or folder and in somewhere where it should not exist or happen.

Otherwise without this feature or capability, Konsistent cannot be a strict or guarding tool, things could go out of rail.

Suggested Implementation

No response

Start by locating how Konsistent processes the MustHave array and validates project directories, then trace where warnings or errors are reported. Define the behavior for files and folders absent from the allowlist, including nested paths, and verify that unexpected entries are consistently rejected or warned about.
