🔧 Fix command syntax inconsistencies and improve documentation clarity

## Command Syntax Standardization
- Fix lowercase "superclaude" → "SuperClaude" in installation.md
- Distinguish between terminal commands (SuperClaude install) and Claude Code commands (/sc:*)
- Add clear command context headers to all major documentation files

## Documentation Improvements
- Add command reference tables to key guides
- Create visual distinction markers (🖥️ Terminal vs 💬 Claude Code)
- Update verification sections with proper command separation
- Fix content duplications in Developer-Guide and Getting-Started files

## Cross-Reference Updates
- Standardize all documentation links to use Docs/ prefix structure
- Replace invalid email addresses with anton.knoery@gmail.com
- Remove non-existent team references from security documentation

## Files Enhanced
- Getting-Started: installation.md, quick-start.md with command clarity
- User-Guide: commands.md with comprehensive command context
- Reference: troubleshooting.md, common-issues.md with mixed command support
- Root files: README.md, CONTRIBUTING.md, SECURITY.md link updates

This resolves command confusion between installation (terminal) and development (/sc:) commands.
