root d697a7bcb5 fix: resolve external LVM boot issues - clean passphrase prompts and GRUB menu ...

CRITICAL BOOT FIXES: Clean external M.2 boot experience

🔧 Issues Resolved:
1. ❌ FIXED: Boot prompting for internal encrypted home partition passphrase
2. ❌ FIXED: Internal drive entries appearing in external GRUB menu
3. ❌ FIXED: Conflicting crypttab and os-prober configurations

🛠️  Technical Changes Applied:
• Cleaned /etc/crypttab - removed internal drive encryption mapping
• Disabled GRUB os-prober - prevents internal drive detection
• Updated initramfs - reflects new crypttab configuration
• Regenerated GRUB config - clean menu with only external entries

📁 New Script Added:
• clean_external_lvm_boot.sh - automates these fixes for future use
• Comprehensive logging and verification
• Safe backup procedures for all modified files

✅ Expected Results After Reboot:
• No passphrase prompts during boot
• Clean GRUB menu with only Kubuntu (external LVM) entries
• Seamless boot directly to external M.2 system
• Complete isolation from internal drive

🎯 Boot Process Now:
1. GRUB loads from external M.2 EFI partition
2. Shows only external LVM kernel options
3. Boots directly without encryption prompts
4. Internal drive remains completely untouched

Critical fix for production-ready external LVM boot system.
