feat: add /sc:implement command and fix documentation consistency

- NEW COMMAND: /sc:implement for feature and code implementation
- Addresses v2 user feedback about /build command functionality change
- Updates command count from 15 to 16 across all documentation
- Adds comprehensive implementation examples and auto-activation patterns
- Includes v2 migration guidance for smooth upgrade path
- Fixes numerical inconsistencies in commands-guide.md, CHANGELOG.md, installation-guide.md

+# /sc:implement - Feature Implementation
+
+## Purpose
+Implement features, components, and code functionality with intelligent expert activation and comprehensive development support.
+
+## Usage
+```
+/sc:implement [feature-description] [--type component|api|service|feature] [--framework react|vue|express|etc] [--safe]
+```
+
+## Arguments
+- `feature-description` - Description of what to implement
+- `--type` - Implementation type (component, api, service, feature, module)
+- `--framework` - Target framework or technology stack
+- `--safe` - Use conservative implementation approach
+- `--iterative` - Enable iterative development with validation steps
+- `--with-tests` - Include test implementation
+- `--documentation` - Generate documentation alongside implementation
+
+## Execution
+1. Analyze implementation requirements and detect technology context
+2. Auto-activate relevant personas (frontend, backend, security, etc.)
+3. Coordinate with MCP servers (Magic for UI, Context7 for patterns, Sequential for complex logic)
+4. Generate implementation code with best practices
+5. Apply security and quality validation
+6. Provide testing recommendations and next steps
+
+## Claude Code Integration
+- Uses Write/Edit/MultiEdit for code generation and modification
+- Leverages Read and Glob for codebase analysis and context understanding
+- Applies TodoWrite for implementation progress tracking
+- Integrates Task tool for complex multi-step implementations
+- Coordinates with MCP servers for specialized functionality
+- Auto-activates appropriate personas based on implementation type
+
+## Auto-Activation Patterns
+- **Frontend**: UI components, React/Vue/Angular development
+- **Backend**: APIs, services, database integration
+- **Security**: Authentication, authorization, data protection
+- **Architecture**: System design, module structure
+- **Performance**: Optimization, scalability considerations
+
+## Examples
+```
+/sc:implement user authentication system --type feature --with-tests
+/sc:implement dashboard component --type component --framework react
+/sc:implement REST API for user management --type api --safe
+/sc:implement payment processing service --type service --iterative
+```
