Fix PAL review findings: documentation accuracy and code quality

- Update CLAUDE.md with complete kernel parameters including boot=netboot
- Remove duplicate wget/curl package declarations in build-image.sh
- Check unsquashfs in both /usr/bin and /usr/sbin in verify-image.sh
- Use consistent $quiet variable expansion in netboot hook functions

All issues identified in zen-opus pre-commit review are now resolved.
