/**
 * Static guard for ruvnet/ruflo#2219 — keep the `better-sqlite3` override
 * pinned to a version that ships Node 24/25/26 prebuilds.
 *
 * Why: `agentdb` declares `better-sqlite3` as an OPTIONAL dependency at
 * `^11.8.1`. better-sqlite3 11.8.1 has no prebuilt binary for Node 24/25/26,
 * so on those runtimes the optional native build fails *silently* (optional
 * deps never error) and AgentDB falls back to a non-persistent backend —
 * users on Node 24/26 saw stores succeed but never persist (silent write
 * loss). better-sqlite3 >=12.8.0 ships prebuilds for Node 20–26.
 *
 * Per the #2112 lesson, root overrides do NOT propagate to the published
 * `ruflo` wrapper — the override MUST be present in BOTH the root umbrella
 * (`package.json`) and the wrapper (`ruflo/package.json`). This guard asserts
 * both carry `better-sqlite3 >= 12.8.0`. Wired into v3-ci.yml.
 *
 * Exit codes:
 *   0 — both overrides present and satisfy >=12.8.0
 *   1 — missing override, or a range that admits a Node-24/26-broken version
