Improve documentation look & feel via MkDocs Material template enhancements (#5)

# Improve documentation look & feel via MkDocs Material template enhancements

## Summary

This MR improves the overall **documentation experience and visual presentation** of the doc-forge docs by enhancing the MkDocs Material template configuration.

The changes focus on **navigation usability, code readability, and richer Markdown rendering**, resulting in a cleaner and more professional documentation site.

Docstring changes were made across the codebase for consistency, but this MR description focuses on the **template and presentation improvements**.

---

## Navigation Improvements

The navigation system has been enhanced to provide a clearer structure and better discoverability.

Key improvements include:

* Section-aware navigation in the sidebar
* Automatic expansion of module/package hierarchy
* Scroll tracking within the sidebar
* Clickable package index pages

Material navigation features added:

* `navigation.sections`
* `navigation.expand`
* `navigation.tracking`
* `navigation.indexes`

This results in a **single cohesive navigation tree** that exposes the entire documentation hierarchy from the sidebar.

---

## Code Block Improvements

Code blocks previously appeared relatively plain. The template now enables richer syntax highlighting and improved readability.

Enhancements include:

* Syntax highlighting using `pymdownx.highlight`
* Line numbers for code blocks
* Anchored line numbers for deep linking
* Improved fenced code block rendering

Additional Material features:

* `content.code.copy` — copy button for code blocks
* `content.code.annotate` — support for code annotations

These changes significantly improve the readability of examples and API snippets throughout the documentation.

---

## Markdown Rendering Enhancements

Additional Markdown extensions were enabled to support richer documentation features:

* `pymdownx.superfences` for advanced fenced blocks
* `pymdownx.inlinehilite` for inline code highlighting
* `pymdownx.snippets` for reusable snippets
* `admonition` and `pymdownx.details` for callouts and collapsible sections
* `pymdownx.tabbed` for tabbed content blocks
* `pymdownx.tasklist` for checklist-style items
* `tables`, `footnotes`, and advanced formatting extensions

These extensions make it easier to write expressive and structured documentation.

---

## Search Experience

The documentation search experience has been improved using Material search features:

* `search.highlight`
* `search.share`
* `search.suggest`

These enhancements provide:

* highlighted search matches
* sharable search URLs
* auto-suggestions while typing

---

## mkdocstrings Improvements

The mkdocstrings configuration has been expanded to produce clearer API documentation.

Notable improvements include:

* grouping objects by category
* explicit category headings
* improved symbol headings
* cleaner object path display

This results in more structured API documentation pages.

---

## Result

Overall, these changes provide:

* cleaner and more intuitive navigation
* significantly improved code presentation
* richer Markdown capabilities
* better search usability

The documentation now has a **more polished, modern appearance** and improved usability for both readers and contributors.
