meta/scripts/verify_shell_split.sh was a scratchpad file; it has caught
five bugs across 18 splits that bash -n and shellcheck both passed on,
so it belongs in the repo. Tested in both directions - it fails on a
deliberately broken source line and passes once restored.
docs/shell-split-recipes.md gains what the last two batches taught:
splitting a file twice can displace the first cut's source line, globals
read across a seam have three different fixes depending on how many, and
unguarded cd shows up constantly because a moved function finally gets
linted on its own.
