/**
 * Curator daemon configuration schema — Sphere B SG-CLEO-SKILLS foundation.
 *
 * Defines the `daemon.curator` config namespace consumed by the (future)
 * curator daemon under SG-CLEO-SKILLS that periodically sweeps `skills.db`
 * to mark stale rows and archive expired ones.
 *
 * Lives in `packages/core/src/sentient/` because the curator is a sentient
 * subsystem peer of the existing `propose-tick` / `dream-cycle` daemons —
 * it reads the global skills.db on a fixed cadence and emits proposals when
 * thresholds are crossed.
 *
 * ## Why a separate module (not contracts/src/config.ts)?
 *
 * The T9683 charter explicitly requires "NEW modules (NO edits to existing
 * public API except adding exports to index.ts)". The Zod schema lives here;
 * the (future) merge into the global {@link CleoConfig} interface will be
 * done in a downstream task that owns the contracts/config.ts touch.
 *
 * ## Validation invariants
 *
 * Beyond per-field type/range checks, the cross-field invariants enforced by
 * {@link curatorConfigSchema} are:
 *
 * 1. `staleAfterDays < archiveAfterDays` — archiving CANNOT happen before
 *    staleness is reached; reversing the order would silently archive rows
 *    that were never marked stale.
 * 2. `runEveryHours >= 1` — sub-hourly cadence is rejected to keep the
 *    daemon's CPU + IO footprint bounded on low-spec hosts (Pi v2/v3 ADR-035).
 *
 * @task T9683
 * @epic T9571
 * @saga T9560
