/**
 * quality-gate — shared retry/bounded-findings gate behind the task-pipeline test-gate
 * wrappers (task 0823, feature I21, governance §1.2 composition budgets).
 *
 * Task 1006 R1: the gate logic moved to packages/app/src/services/quality-gate.ts (unit-tested
 * there); this script is ADR-130 glue — argv/env parsing only — over the bundled core in
 * ../lib/quality-gate.generated.* (regenerate: `bun run build:plugin-lib && bun run build:scripts`).
 *
 * Behavioral contract (unchanged): modes run|recheck|light|status (env: wbs, qualityGateCmd,
 * gateProbeCmd, proofDigest, runId); exit 0 on PASS/reuse, 1 on FAIL, 2 on usage error; the
 * `{reuse, reason}` JSON stays the last stdout line in status mode. Invoked from
 * task-pipeline.yaml via `superskill script path sp quality-gate.mjs` — keep the committed twin
 * in lockstep.
