/******************************************************************************************
* Helper: Idempotent constraint rename for H2
* H2 does not support RENAME CONSTRAINT IF EXISTS, so we create a Java alias that
* executes a rename and suppresses error 90057 (constraint not found).
* NOTE: Do not declare method as public static; H2 wraps it and adds modifiers itself.
* (Updated) Use precompiled Java class instead of inline Java to avoid needing 'javac' at runtime.
* Class: org.gameyfin.db.h2.H2Aliases.renameConstraintIfExists(Connection,String,String,String)
