Review-assist for #324 under the Bitgesell improvement queue (#81):

• Scope looks appropriately narrow: force LC_ALL=C before shell-sensitive commands so test/lint/lint-shell-locale.py stops depending on host locale state.
• The most important acceptance point is making sure the changed scripts are exactly the ones the lint rule inspects. A quick paste of the python3 test/lint/lint-shell-locale.py output in the PR would make the intended coverage explicit.
• Because this touches mixed sh/bash entrypoints and CI helpers, I would also sanity-check that moving LC_ALL=C ahead of set -eux in ci/retry/retry.sh is the only ordering-sensitive change and that no script relies on locale-specific sort/grep behavior elsewhere.
• contrib/macdeploy/detached-sig-create.sh and share/qt/extract_strings_qt.py wrappers are good places for an extra smoke note, since packaging / string-extraction scripts often fail only on contributor machines rather than CI.
• If maintainers consider this part of the #81 paid improvement lane, it would help to confirm the expected payout/claim path once the validation note is added.
