[Feature]: Need docs/design/introduction.md

[Malcolmnixon]

Problem Statement

The docs/design/introduction.md needs to be created covering the high-level design software units.

Proposed Solution

A good example of a design-introduction can be found at https://raw.githubusercontent.com/demaconsulting/ReqStream/refs/heads/main/docs/design/introduction.md and includes the key elements of the Software Structure and Folder Layout.

Don't write what's in the repository now, but write the software structure and folder layout as it would appear in the finished project. Plan the final implementation including the Software-System, Software-Subsystems, and Software-Units (see your own standards document for definitions at https://raw.githubusercontent.com/demaconsulting/FileAssert/refs/heads/main/.github/standards/software-items.md)
