git clean -fd scopes to the current directory and below, so running it
from the system_setup/ subdirectory missed untracked files in sibling
dirs like config/. Use -C "${SYSCONFIGPATH}" to always clean from the
repo root regardless of invocation directory.

Replace the broken `git rebase HEAD^` with a proper shallow fetch:
- `git fetch --depth=1` limits local history to one commit, regardless of server history
- `git reset --hard FETCH_HEAD` syncs the working tree to the fetched tip
- `git clean -fd` removes untracked non-ignored files left by old versions
- `git gc --prune=now` immediately purges unreachable history objects
