- uninstall.sh: track _restore_failed separately from RESTORED so
"No backup files found" only prints when find returns nothing (not
when mv fails on existing backups); abort with exit 1 before rm -rf
when any restore fails, leaving PATCH_DIR and recover.sh intact
- install.sh: extend log-scan grep to catch ERROR: lines from
patch_ui.py (backup OSError was silently missed by WARNING:-only grep)
- install.sh: reword restart-failure message — hook IS already
registered and sitecustomize.py IS installed; patch activates on
next boot regardless
- apply.sh: replace `if $_can_install` with `[ "$_can_install" = true ]`
(explicit test, no implicit command lookup); drop 2>/dev/null on
install cp so OS error detail reaches the log
