Consolidate workflows and tools from commands repository

Repository Restructure:
- Move all 83 agent .md files to agents/ subdirectory
- Add 15 workflow orchestrators from commands repo to workflows/
- Add 42 development tools from commands repo to tools/
- Update README for unified repository structure

The commands repository functionality is now fully integrated, providing
complete workflow orchestration and development tooling alongside agents.

Directory Structure:
- agents/    - 83 specialized AI agents
- workflows/ - 15 multi-agent orchestration commands
- tools/     - 42 focused development utilities

No breaking changes to agent functionality - all agents remain accessible
with same names and behavior. Adds workflow and tool commands for enhanced
multi-agent coordination capabilities.

+Perform comprehensive multi-agent code review with specialized reviewers:
+
+[Extended thinking: This tool command invokes multiple review-focused agents to provide different perspectives on code quality, security, and architecture. Each agent reviews independently, then findings are consolidated.]
+
+## Review Process
+
+### 1. Code Quality Review
+Use Task tool with subagent_type="code-reviewer" to examine:
+- Code style and readability
+- Adherence to SOLID principles
+- Design patterns and anti-patterns
+- Code duplication and complexity
+- Documentation completeness
+- Test coverage and quality
+
+Prompt: "Perform detailed code review of: $ARGUMENTS. Focus on maintainability, readability, and best practices. Provide specific line-by-line feedback where appropriate."
+
+### 2. Security Review
+Use Task tool with subagent_type="security-auditor" to check:
+- Authentication and authorization flaws
+- Input validation and sanitization
+- SQL injection and XSS vulnerabilities
+- Sensitive data exposure
+- Security misconfigurations
+- Dependency vulnerabilities
+
+Prompt: "Conduct security review of: $ARGUMENTS. Identify vulnerabilities, security risks, and OWASP compliance issues. Provide severity ratings and remediation steps."
+
+### 3. Architecture Review
+Use Task tool with subagent_type="architect-reviewer" to evaluate:
+- Service boundaries and coupling
+- Scalability considerations
+- Design pattern appropriateness
+- Technology choices
+- API design quality
+- Data flow and dependencies
+
+Prompt: "Review architecture and design of: $ARGUMENTS. Evaluate scalability, maintainability, and architectural patterns. Identify potential bottlenecks and design improvements."
+
+## Consolidated Review Output
+
+After all agents complete their reviews, consolidate findings into:
+
+1. **Critical Issues** - Must fix before merge
+   - Security vulnerabilities
+   - Broken functionality
+   - Major architectural flaws
+
+2. **Important Issues** - Should fix soon
+   - Performance problems
+   - Code quality issues
+   - Missing tests
+
+3. **Minor Issues** - Nice to fix
+   - Style inconsistencies
+   - Documentation gaps
+   - Refactoring opportunities
+
+4. **Positive Findings** - Good practices to highlight
+   - Well-designed components
+   - Good test coverage
+   - Security best practices
+
+Target for review: $ARGUMENTS
