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.

+Optimize application stack using specialized optimization agents:
+
+[Extended thinking: This tool coordinates database, performance, and frontend optimization agents to improve application performance holistically. Each agent focuses on their domain while ensuring optimizations work together.]
+
+## Optimization Strategy
+
+### 1. Database Optimization
+Use Task tool with subagent_type="database-optimizer" to:
+- Analyze query performance and execution plans
+- Optimize indexes and table structures
+- Implement caching strategies
+- Review connection pooling and configurations
+- Suggest schema improvements
+
+Prompt: "Optimize database layer for: $ARGUMENTS. Analyze and improve:
+1. Slow query identification and optimization
+2. Index analysis and recommendations
+3. Schema optimization for performance
+4. Connection pool tuning
+5. Caching strategy implementation"
+
+### 2. Application Performance
+Use Task tool with subagent_type="performance-engineer" to:
+- Profile application code
+- Identify CPU and memory bottlenecks
+- Optimize algorithms and data structures
+- Implement caching at application level
+- Improve async/concurrent operations
+
+Prompt: "Optimize application performance for: $ARGUMENTS. Focus on:
+1. Code profiling and bottleneck identification
+2. Algorithm optimization
+3. Memory usage optimization
+4. Concurrency improvements
+5. Application-level caching"
+
+### 3. Frontend Optimization
+Use Task tool with subagent_type="frontend-developer" to:
+- Reduce bundle sizes
+- Implement lazy loading
+- Optimize rendering performance
+- Improve Core Web Vitals
+- Implement efficient state management
+
+Prompt: "Optimize frontend performance for: $ARGUMENTS. Improve:
+1. Bundle size reduction strategies
+2. Lazy loading implementation
+3. Rendering optimization
+4. Core Web Vitals (LCP, FID, CLS)
+5. Network request optimization"
+
+## Consolidated Optimization Plan
+
+### Performance Baseline
+- Current performance metrics
+- Identified bottlenecks
+- User experience impact
+
+### Optimization Roadmap
+1. **Quick Wins** (< 1 day)
+   - Simple query optimizations
+   - Basic caching implementation
+   - Bundle splitting
+
+2. **Medium Improvements** (1-3 days)
+   - Index optimization
+   - Algorithm improvements
+   - Lazy loading implementation
+
+3. **Major Optimizations** (3+ days)
+   - Schema redesign
+   - Architecture changes
+   - Full caching layer
+
+### Expected Improvements
+- Database query time reduction: X%
+- API response time improvement: X%
+- Frontend load time reduction: X%
+- Overall user experience impact
+
+### Implementation Priority
+- Ordered list of optimizations by impact/effort ratio
+- Dependencies between optimizations
+- Risk assessment for each change
+
+Target for optimization: $ARGUMENTS
