/**
 * Regression test for bug #2439
 *
 * /gsd-set-profile crashed with `command not found: gsd-sdk` when the
 * gsd-sdk binary was not installed or not in PATH. The command body
 * invoked `gsd-sdk query config-set-model-profile` directly with no
 * pre-flight check, so missing gsd-sdk produced an opaque shell error.
 *
 * Fix mirrors bug #2334: guard the invocation with `command -v gsd-sdk`
 * and emit an install hint when absent.
