Add build scripts and Windows icon/resources

Added:
- build_dev.bat / build_dev.sh - Development build scripts
- build_release.bat / build_release.sh - Release build scripts with embedding
- icon.ico - Default Windows icon for executable
- resources.rc - Windows resource file for icon and exe metadata
- BUILD_SCRIPTS.md - Complete documentation for build scripts

Features:
- Automated development builds (no embedding, fast iteration)
- Automated release builds (with Lua and asset embedding)
- Interactive verification and cleanup
- Custom icon and version info in Windows executables
- Cross-platform scripts (Windows .bat and Unix .sh)
- Safety checks and helpful messages

The build scripts provide one-command building for both development
and release workflows, with clear instructions and progress feedback.
