/**
 * Static guard for ruvnet/ruflo#2127 (and the family of #1147 / #2018).
 *
 * The reporter hit `TypeError: Invalid Version: (empty)` inside arborist's
 * `canDedupe` while installing `ruflo@3.8.0`. Two reviewers could not
 * reproduce, but the published `ruflo` wrapper still pinned
 * `"@claude-flow/cli": "^3.7.0-alpha.11"` long after the project moved to
 * stable semver. That pre-release range widens the resolution space the
 * dedupe pass has to walk and gives more chances for an upstream
 * malformed dep to surface as an empty version comparison.
 *
 * This audit asserts:
 *
 *   1. The `ruflo` wrapper's `@claude-flow/cli` dep range INCLUDES the
 *      version that `v3/@claude-flow/cli` currently publishes.
 *
 *   2. The root `claude-flow` umbrella's sibling deps that we maintain
 *      (`@claude-flow/cli-core`, `@claude-flow/mcp`, `@claude-flow/neural`,
 *      `@claude-flow/shared`) likewise include their actual published
 *      versions (best-effort — only when the corresponding workspace
 *      package.json is present locally).
 *
 *   3. The `ruflo` wrapper does NOT carry a pre-release range
 *      (`-alpha.N` / `-beta.N`) for `@claude-flow/cli` once that package
 *      is publishing stable versions. Pre-release ranges on stable deps
 *      are the specific shape that caused #2127.
 *
 * Failure modes return non-zero with a clear remediation. Runs in CI on
 * every PR via v3-ci.yml `wrapper-dep-ranges-audit` job.
