PR #2038 added detect-custom-files to gsd-tools.cjs and the backup_custom_files
step to update.md, but commit 7bfb11b6 is not an ancestor of v1.36.0: main was
rebuilt after the merge, orphaning the change. Users on 1.36.0 running /gsd-update
silently lose any locally-authored files inside GSD-managed directories.
Root cause: git merge-base 7bfb11b6 HEAD returns aa3e9cf (Cline runtime, PR #2032),
117 commits before the release tag. The "merged" GitHub state reflects the PR merge
event, not reachability from the default branch.
Fix: re-apply the three changes from 7bfb11b6 onto current main:
- Add detect-custom-files subcommand to gsd-tools.cjs (walk managed dirs, compare
against gsd-file-manifest.json keys via path.relative(), return JSON list)
- Add 'detect-custom-files' to SKIP_ROOT_RESOLUTION set
- Restore backup_custom_files step in update.md before run_update
- Restore tests/update-custom-backup.test.cjs (7 tests, all passing)
