// Marks open engineering-initiated issues (label `~engineering-initiated`) as stale after 1y of
// inactivity, and closes them after 14 more days. Invoked by `actions/github-script` from
// `.github/workflows/close-stale-eng-initiated-issues.yml`.
//
// This is a thin wrapper over `stale-issues-core.js`: it provides label-based eligibility and the
// eng-initiated thresholds and wording. The scanning, labeling, closing, and un-staling logic all
// live in the core. The sibling `stale-fleetie-issues.js` wraps the same core with author-based
// eligibility.
//
// Why this replaced `actions/stale`: that action posts a single static stale comment with no way to
// template the issue author, so it could not @-mention the author. The core lets us build the
// comment per issue. Behavior otherwise matches the previous `actions/stale` config (365d to stale,
// 14d to close, remove-stale-when-updated).
//
// Inputs (env):
//   DRY_RUN         'true' to log candidates without writing (read by the core).
//   MAX_OPERATIONS  Cap on API write operations per run. Default 400. `0` disables writes / dry-runs (read by the core).
//
// Exports: `async function run({ github, context, core })`. Returns a summary object for tests.
