Docs Overhaul

[wallstop]

The docs were way too braggy. I tried to tone things down a bit.

Pull request overview

This PR modernizes the documentation by removing overly enthusiastic marketing language and replacing it with more objective, professional descriptions. The changes make the documentation more informative and less sales-focused while maintaining technical accuracy.

Changes:

• Toned down marketing language throughout all documentation files (README.md, VisualGuide.md, and others)
• Added comprehensive Testing.md documentation file with test examples and best practices
• Updated DI integration guides (Zenject, VContainer, Reflex) with clearer namespace import instructions
• Added new CI workflows for spellcheck and actionlint validation
• Updated asset file reference in Samples~/DI/README.md to match renamed file
• Replaced text-based decision flowchart with mermaid diagram in README.md
