SQL-to-RQL transpiler. Tokenises, parses, and emits a SQL statement into the equivalent RQL surface so callers who arrive with a SQL query can submit it to an engine that natively speaks RQL. Coverage is intentionally narrow: the goal is to support the SQL dialects existing tooling produces (SELECT, INSERT, UPDATE, DELETE, basic DDL), not to be a full ANSI implementation.
The crate produces RQL text rather than a planner-internal tree on purpose - the boundary stays at the source level, so SQL behaviour can be verified by reading the emitted RQL and the resulting RQL diagnostics carry the source span the user submitted.
