Harden apply-patches.sh and sync-upstream.sh against local/ data loss

Browse Source 
apply-patches.sh: add --dry-run flag, make patch conflicts fail loudly instead of silently skipping, back up WIP directories instead of rm -rf, refuse to overwrite existing config files. sync-upstream.sh: add --force flag, abort on uncommitted local/ changes unless forced, stash with -u for untracked file protection, add pre-rebase overlay integrity check, improve nuclear option and stash pop guidance.
