icydb-cli 0.179.3

//! Module: SQL shell tests.
//! Responsibility: exercise shell input normalization, routing, decoding, and output rendering.
//! Does not own: top-level clap parsing or ICP process command construction.
//! Boundary: test-only assertions over shell helpers and decoded SQL payload text.
