CVE-2026-53784: confine the daemon's absolute chdir target with a new
ownership-walk resolver so a planted parent symlink cannot steer a
"use chroot = no" module root outside the module
CVE-2026-53786: strip a real module_dir prefix before the daemon-filter
check on a merge-file path -- leaving the daemon's own "include from" /
"exclude from" paths alone -- and treat a hidden merge file as
non-existent
CVE-2026-53803: open the batch stream and replay script, motd, lock,
log and config files through the ownership-walk resolver, and refuse a
non-regular --read-batch file
CVE-2026-53789: clean a requested path's trailing slash and keep an
implied-parent directory non-content, blocking --delete widening
CVE-2026-70459: reject a non-directory transfer-root entry
