KaifAhmad1 9113ef3428 docs: premium overhaul of all reference pages and core docs
- Rewrote all 26 reference module pages: removed blockquote taglines and
  horizontal rule separators, added "What You Get" bullet summaries,
  added constructor/method parameter tables, expanded thin files
  (graph_store, triplet_store, visualization, provenance) with full API
  coverage, added backend comparison tables and real-world usage patterns
- Renamed Modules tab from "API Reference" and group from "Context &
  Knowledge" to "Context & Intelligence" in docs.json
- Fixed logo: copied "Semantica Logo.png" to web-safe semantica-logo.png
  and updated all 4 references in docs.json
- Improved core docs (index, modules, concepts, quickstart, installation,
  getting-started) with better fonts, bullet points, and complete module
  listings (mcp_server, evals, core, utils previously missing)
- Rewrote community pages (community, community-projects, contributing-guide,
  use-cases, architecture, faq, learning-more, glossary) with heading
  hierarchy fixes, expanded definitions, and better structure
- Fixed markdown linter warnings: MD036 bold-as-heading, MD001 heading
  skips, MD040 missing code fence language, MD032 blank lines around lists

## Install from Source
For the latest development version or to contribute:
```bash
git clone https://github.com/semantica-agi/semantica.git
cd semantica
pip install -e . # core only
pip install -e ".[all]" # all extras
pip install -e ".[dev]" # dev tools (pytest, black, etc.)
```
Install directly from the main branch if the PyPI release has issues:
```bash
pip install git+https://github.com/semantica-agi/semantica.git@main
```
## Troubleshooting
### ModuleNotFoundError
Make sure you're in the right environment:
```bash
pip list | grep semantica
pip install --upgrade semantica
```
### Installation fails with dependency errors
```bash
pip install --upgrade pip
pip install build wheel
pip install semantica --no-deps # install without optional deps first
```
### GPU dependencies fail
Install CPU-only first, then add GPU support:
```bash
pip install semantica
pip install semantica[gpu]
```
### Permission denied
```bash
pip install --user semantica # or use a virtual environment
```
### Windows `[all]` install fails
This was fixed in **v0.5.0**. Upgrade to the latest release:
```bash
pip install --upgrade semantica
```
### Windows PyTorch DLL errors
Install the [Microsoft Visual C++ Redistributable](https://aka.ms/vs/17/release/vc_redist.x64.exe). This is a Windows system dependency, not a Semantica bug.
