/**
 * Static guard for ruvnet/ruflo#2151 — enforce three-way version lockstep
 * across the umbrella packages that ship together:
 *
 *   - @claude-flow/cli  (v3/@claude-flow/cli/package.json)
 *   - claude-flow       (root package.json — umbrella)
 *   - ruflo             (ruflo/package.json — thin user-facing wrapper)
 *
 * Why: when these drift (e.g. ruflo@3.10.2 but cli@3.10.1, observed in
 * #2151), `npx ruflo --version` prints the bundled CLI's version (3.10.1),
 * not the wrapper's package.json version (3.10.2). Users see the "wrong"
 * version and reasonably assume the install is broken.
 *
 * The Publishing Rules in CLAUDE.md require all three to ship at the same
 * version. This audit enforces that locally so a drift can't reach a
 * release. Wired into v3-ci.yml as `umbrella-version-lockstep-audit`.
 *
 * Also asserts ruflo's @claude-flow/cli dep range INCLUDES the cli's
 * actual version (overlap with audit-wrapper-dep-ranges.mjs is intentional;
 * this audit is about identity, that one is about inclusion).
 *
 * Exit codes:
 *   0 — versions identical and dep range covers cli
 *   1 — drift detected; remediation hints printed
