/**
* Reconcile the "Interview Prep" Project's Set and Difficulty fields from the
* labels on each problem issue.
*
* The issue labels are the truth: `set:core|optional|deferred` and
* `diff:easy|medium|hard` are fixed when a problem issue is filed, and the
* Project's single-selects are a projection of them so the board can group and
* filter. This recomputes every desired value from scratch and writes only the
* ones that differ, so re-runs are no-ops and a backfill needs no special
* casing — same reconcile-don't-react shape as close-solved / close-topics.
*
* Scope guard: only items whose issue carries the `problem` label are touched.
* Topic, cadence and review issues have no set or difficulty, so they are
* skipped outright — never written, never cleared.
*
* Deliberately NOT mirrored: SRS stage and first-attempt result. Those live
* only in D1 (apps/api owns them; the charts, digest and /api/stats read them
* from there). The Project mirror writes Target Date and nothing else.
*
* Auth: needs a token carrying the `project` scope — neither the default
* `gh auth token` nor Actions' GITHUB_TOKEN has it. Pass one in GH_TOKEN: the
* PROJECT_PAT secret in CI, or the Worker's GH_PAT locally:
* GH_TOKEN=$GH_PAT bun run sync-project-fields -- --dry-run
