Opinionated recipe that builds on UpgradeToJava25 with additional best practices: NoGuava, JSpecify, targeted UseVar, and broadly accepted static analysis improvements.
PrimitiveWrapperClassConstructorToValueOf and BigDecimalRoundingConstantsToEnums are already included transitively via Java8toJava11.
Add stdlib preference recipes (UseEnumSetOf, UseListOf, UseSetOf, UseStringIsEmpty), bug prevention (ReplaceWeekYearWithYear, RemoveHashCodeCallsFromArrayInstances, RemoveToStringCallsFromArrayInstances, UseObjectNotifyAll, RemoveCallsToSystemGc, RemoveCallsToObjectFinalize), and modernization (UseStandardCharset, UseSystemLineSeparator, RemoveRedundantTypeCast, ReplaceStackWithDeque, UseListSort, EqualsToContentEquals).
Removed UseStringIsEmptyRecipe from Java best practices.
UseVarForGenericsConstructors/UseVarForGenericMethodInvocations must run before UseDiamondOperator to preserve the explicit type arguments needed for var inference.
