…#139175) Fixes circular reference detection in alias chains during `DeduplicateAggs` optimizations. The `PushDownEnrich` optimization can create circular references when pushing `Enrich` past `Project` operations, causing `ql_illegal_argument_exception: Potential cycle detected` errors when `DeduplicateAggs`. Example query: ```esql FROM languages_lookup | RENAME language_name AS message | ENRICH languages_policy ON language_code | STATS a = count(to_lower(language_name)), b = count(language_name) ``` Skip aliases that would create circular references by checking if `alias.toAttribute()` equals the resolved `alias.child()`. Closes elastic#138346 Closes elastic#139541 (cherry picked from commit 2289e17)
