- t/C4/ClassSplitRoutine/RegEx.t (new): exercises _apply_substitution via
the public split_callnumber interface — basic substitution, alternate
delimiters, \n/$n backrefs, /gi combined flag, /e rejection, and malformed
or uncompilable rules (including the new logger warn path).
- t/Koha/Regex/Replacement.t: extend the subst() helper to handle the ig/gi
combined modifier and add a subtest that confirms case-insensitive global
replacement and backref case preservation.
