🔧 Standardize agent invocation syntax: @agents- → @agent-

## Changes Made
- **Agent Syntax Standardization**: Updated all agent invocations from `@agents-` to `@agent-`
- **Consistency**: Applied change across all 14 documentation files and 1 source file
- **Examples Updated**: All agent invocation examples now use singular `@agent-` format
- **Pattern Recognition**: Updated references to trigger pattern documentation

## Files Updated (14 total)
### Documentation
- Docs/User-Guide/commands.md - Core command reference
- Docs/User-Guide/agents.md - Agent guide with all examples
- Docs/README.md - Quick reference updated
- Docs/Getting-Started/installation.md & quick-start.md - Setup instructions
- Docs/Developer-Guide/ - Technical architecture and testing docs
- Docs/Reference/ - All example files and troubleshooting

### Source Files
- SuperClaude/Agents/security-engineer.md - Agent context file

## Impact
✅ **Consistent Syntax**: All agent invocations now use `@agent-[name]` format
✅ **User Clarity**: Clear distinction from previous `@agents-` plural form
✅ **Documentation Alignment**: All examples and references updated consistently
✅ **Framework Standards**: Aligns with SuperClaude naming conventions

Examples now correctly show:
- `@agent-security "review authentication"`
- `@agent-python-expert "optimize code"`
- `@agent-frontend-architect "design components"`

Total replacements: 80+ instances across entire documentation
