Module maturity: Add minimum README + setup/run/test status

[rishabhhinduja]

Some modules have incomplete or placeholder docs, making them hard to understand or use.

Examples:

Medi_Predict/Readme.md → almost empty
Dsa_Visualizer/Idea.md → idea only, no implementation details
Geospatial Civic Engine for Climate Response/README.md → license TBD, contribution guide incomplete

Problem:

Poor onboarding
Unclear module status
Hard to run/test modules

Solution:
Add a minimum README for every module including:

Overview
Current status (Idea / In Progress / Functional)
Setup & run instructions
Testing status
(Optional) Contribution + license

Acceptance Criteria:

Every module has a meaningful README.md
No placeholder text like “coming soon”
Clear setup/run/test info for each module
