initramfs: fix rootless perms for etc/zinit and add diagnostics

• Ensure host/rootless traversal for zinit configs: make etc/zinit and etc/zinit/init 755 prior to recursive normalization; then set dirs=755, files=644, and mark *.sh executable in [bash.initramfs_setup_zinit()](scripts/lib/initramfs.sh:12)

• Add pre-CPIO sanity logs to catch empty/mis-scoped archives: top-level ls, file count, and essential presence checks in [bash.initramfs_create_cpio()](scripts/lib/initramfs.sh:658)

• Add validation-time sanity snapshot of top-level and entry count in [bash.initramfs_validate()](scripts/lib/initramfs.sh:754)
