Module sql_lowering 

Filter ⇄ Expr lowering — re-export shim.

The lowering helpers (filter_to_expr, expr_to_filter, projection_to_*, the effective_* accessors, …) moved into the reddb-io-rql crate alongside the canonical SQL AST they operate on (#1113, ADR 0053): they depend only on the AST plus reddb-io-types, so they belong in the same dependency-closed cluster. This shim preserves the historical crate::storage::query::sql_lowering::* import path so every parser, planner, and runtime call-site keeps resolving unchanged.
