/**
 * #2589 — config-get / resolve-model / verification.status lookups must not
 * depend on jq.
 *
 * The workflows resolved configured scalars / model ids / verify status with a
 * `gsd_run query <cmd> … | jq … 2>/dev/null || <default>` shape. On any machine
 * without jq (the default on Windows / Git-Bash) the jq stage fails with exit
 * 127, that failure is swallowed by `2>/dev/null` and the trailing `|| default`,
 * so the variable comes back EMPTY — the configured value is silently dropped
 * and the lane falls back to CLI defaults with no diagnostic.
 *
 * gsd-tools ships native flags that do the same job with no external dep:
 *   config-get <key> --raw          (strips JSON quotes off a scalar)
 *   resolve-model <id> --pick model (descends an object)
 *   verification.status <dir> --pick status
 *
 * This is a SOURCE-INVARIANT test over the shipped workflow documents: the bug
 * lives in the workflow text, so the regression guard asserts the jq-dependent
 * shapes never return. Workflow .md files are runtime-loaded config documents,
 * so reading them with readFileSync + regex is the sanctioned seam here (the
 * no-source-grep lint targets src/ + bin/lib/, not config/state docs).
