## Which issue does this PR close? Validation prerequisite for the semi-join optimization draft. ## Rationale for this change Clippy reports mutable-key-type on three existing window-expression sets because Expr contains interior-mutable memory reservations. Those reservations do not participate in equality or hashing. ## What changes are included in this PR? Allow mutable-key-type at the three affected declarations and document why their keys remain stable. ## What is the testing strategy for this PR? All-target, all-feature Clippy passes. This changes no executable behavior; existing window pushdown tests cover the affected code. ## Are there any user-facing changes? None.
