Fix 32-bit bcrypt ELFCLASS64 error and enhance installation
- Enhanced install_32bit.sh with clean virtual environment creation - Added --force-reinstall and --clear flags for proper isolation - Improved download_32bit_libs.sh with explicit armv7l targeting - Added troubleshoot_32bit.sh for diagnosing 32-bit issues - Better architecture verification and error messages - Comprehensive package testing after installation Fixes ELFCLASS64 error on 32-bit systems by ensuring proper architecture isolation and clean package installation.
