// TestExternalDialectHasNoBackendOrGinDependency is the compiler/boundary proof
// that the SOQL dialect module is seal-clean: it must not transitively depend on
// github.com/nexuscrm/backend OR github.com/gin-gonic/gin. SOQL is an L1
// (Salesforce query LANGUAGE) concern that lives ABOVE the L0 contract, so it is
// now a compatibility adapter over the independently publishable, stdlib-only
// sfcrm/querycodec plus the legacy shared request types consumed by the
// transitional dialect. This makes the parser's single L1 owner a compile fact
// instead of leaving a second copy in the compatibility module. Run under
// GOWORK=off in CI so workspace replacements cannot mask a dependency leak.
