feat: Create a documentation site using Sphinx or MkDocs

[nitinc264]

Our project currently lacks a proper, version-controlled documentation site. This makes it difficult to maintain and for new contributors to get started.

The Goal:
Migrate our documentation (currently in Word files or the README) to a dedicated documentation site generator like Sphinx or MkDocs.

Why This Is Important:

• Easier to version, review, and collaborate on documentation.
• Generates a clean, professional HTML site.
• Allows us to auto-generate API documentation from our Python docstrings.
• Integrates perfectly with GitHub Pages or Read the Docs for free hosting.

Tasks:

1. Choose a generator (MkDocs is recommended for its simplicity and Markdown-based approach).
2. Initialize the new documentation structure (e.g., a docs/ folder).
3. Migrate any existing documentation from the README (or other files) into the new structure.
4. Set up a clean navigation structure in the config file (e.g., mkdocs.yml).
5. (Optional but recommended) Set up mkdocstrings to automatically pull in documentation from the Python code.
6. Set up a deployment method (e.g., GitHub Pages).

Acceptance Criteria:

• A docs/ directory exists with a working mkdocs.yml (or Sphinx conf.py).
• The documentation site builds successfully without errors.
• The site is published and accessible via a GitHub Pages URL.
