fix: resolve kernel module installation and packaging issues

- Fixed resolve-module-dependencies.sh to handle missing modules gracefully
- Removed destructive 'set -e' behavior that caused immediate exit on missing modules
- Enhanced install-firmware-minimal.sh to handle partial success scenarios
- Fixed install-packages.sh to preserve installed kernel modules (was deleting them)
- Improved setup-initramfs.sh to ensure modules directory always exists
- Now successfully installs 43 essential kernel modules in final initramfs
- Fixes 'depmod: ERROR: could not open directory /lib/modules' boot issue

All kernel modules (.ko files) are now properly included in the final cpio archive.
