feat: Major refactoring and improvements v2.11.0

## 🚀 Major Improvements

### Docker Environment Simplification
- **BREAKING**: Simplified Docker configuration by auto-detecting sandbox from WORKSPACE_ROOT
- Removed redundant MCP_PROJECT_ROOT requirement for Docker setups
- Updated all Docker config examples and setup scripts
- Added security validation for dangerous WORKSPACE_ROOT paths

### Security Enhancements
- **CRITICAL**: Fixed insecure PROJECT_ROOT fallback to use current directory instead of home
- Enhanced path validation with proper Docker environment detection
- Removed information disclosure in error messages
- Strengthened symlink and path traversal protection

### File Handling Optimization
- **PERFORMANCE**: Optimized read_files() to return content only (removed summary)
- Unified file reading across all tools using standardized file_utils routines
- Fixed review_changes tool to use consistent file loading patterns
- Improved token management and reduced unnecessary processing

### Tool Improvements
- **UX**: Enhanced ReviewCodeTool to require user context for targeted reviews
- Removed deprecated _get_secure_container_path function and _sanitize_filename
- Standardized file access patterns across analyze, review_changes, and other tools
- Added contextual prompting to align reviews with user expectations

### Code Quality & Testing
- Updated all tests for new function signatures and requirements
- Added comprehensive Docker path integration tests
- Achieved 100% test coverage (95 tests passing)
- Full compliance with ruff, black, and isort linting standards

### Configuration & Deployment
- Added pyproject.toml for modern Python packaging
- Streamlined Docker setup removing redundant environment variables
- Updated setup scripts across all platforms (Windows, macOS, Linux)
- Improved error handling and validation throughout

## 🔧 Technical Changes

- **Removed**: `_get_secure_container_path()`, `_sanitize_filename()`, unused SANDBOX_MODE
- **Enhanced**: Path translation, security validation, token management
- **Standardized**: File reading patterns, error handling, Docker detection
- **Updated**: All tool prompts for better context alignment

## 🛡️ Security Notes

This release significantly improves the security posture by:
- Eliminating broad filesystem access defaults
- Adding validation for Docker environment variables
- Removing information disclosure in error paths
- Strengthening path traversal and symlink protections
