docs: Improve the readme of this repo

[LisoUseInAIKyrios]

Feature description

Readme is mostly empty right now but it could explain:

• How Morphe works (can be similar or identical language as the website)
• Where to download Morphe (link to latest GitHub releases)

Motivation

Help new users who start here and are a bit overwhelmed with the complexity of GitHub.

Acknowledgements

• I have checked all open and closed feature requests and this is not a duplicate.
• I have chosen an appropriate title.
• The feature request is only related to Morphe (Manager).

Readme can also show an expandable patches list like RVX does.
