Add build automation scripts and test infrastructure improvements

Adds PowerShell build script (build.ps1) for Windows with cross-platform Makefile enhancements. Both scripts provide unified commands for dependency installation, testing, linting, formatting, and Docker operations with automatic prerequisite checks.

Makefile improvements:
- Dependency detection for Node.js, npm, and .NET CLI
- New targets: install, test, lint, format, check-deps
- Enhanced error messages for missing dependencies
- Docker
