When a QueryBuilder alias like 'event' coincidentally matches an existing PHP class name (e.g. \Event from ext-event stubs), isClassString() returns yes and isTransient() returns true, causing a DynamicQueryBuilderArgumentException. This made the query type resolve to mixed instead of the correct entity type. Invert the transient check so that only non-transient (actual entity) class-strings are resolved to their FQCN. Transient class-strings now fall through to constant scalar handling, where they are treated as plain string aliases. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

When a QueryBuilder alias like 'event' coincidentally matches an
existing PHP class name (e.g. \Event from ext-event stubs),
isClassString() returns yes and isTransient() returns true, causing
a DynamicQueryBuilderArgumentException. This made the query type
resolve to mixed instead of the correct entity type.
The
isTransientcheck inArgumentsProcessor::processArgs()is now scoped to only the firstargument of from/join/innerJoin/leftJoin/rightJoin methods. For all other methods and argument
positions, class-strings that happen to match a PHP class name fall through to constant scalar
handling. This preserves the error for genuinely passing a non-entity class to from/join, while
fixing the false positive for aliases like 'event'.
