Subject: [PATCH] Fix Strong's cross-language derivation links
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Hebrew numbers in Greek derivations often have leading zeros (H04566)
which caused lookups to fail. Now normalize all Strong's numbers by
stripping leading zeros before lookup and link generation.
