chore(changeset): grade @objectstack/client minor, not patch

Check Changeset: a PR declaring clause-② yes may not grade a package it

 The auth route ledger's `GET /api/v1/auth/organization/get-active-member` row is rebooked from `sdk` to `server-only` in the same change: `sdk` means "expressed by the SDK", and no SDK method builds that URL any more. Ledger-internal, nothing published moves with it.
