/**
 * Release a legal hold (`DELETE /v1/legal-holds/{hold_id}`). TERMINAL: there is no un-release
 * (a reopened matter needs a new hold); once no active hold covers a person, Granola's normal
 * deletion rules apply to their notes again. Releasing twice returns the original `released_at`.
 * WRITE: previews unless `confirm: true` (the preview shows the hold being released).
 *
 * @param input.account - Account whose secret holds a Legal hold API key. Required. @param input.secretName - Secret override.
 * @param input.holdId - `lgh_…` id. Required.
 * @param input.dryRun - Preview only. @param input.confirm - `true` to release.
 * @returns Preview `{ dryRun: true, current, request }`, or `{ executed: true, result: { id, released: true, released_at } }`
 *
 * @example
 * import releaseHold from 'kody:@charlesmatte/granola/legal-holds/release'
 *
 * const preview = await releaseHold({ account: 'work-legal', holdId: 'lgh_Abc123XyZ456Dq' })
