chore(changeset): patch @objectstack/client — the docblock ships in dist/*.d.ts

Measured rather than assumed: `@objectstack/client`'s `files[]` is
["dist","README.md","CHANGELOG.md"], and after `pnpm --filter
@objectstack/client build` the new docblock prose is present in both
dist/index.d.ts and dist/index.d.mts (positive control: the pre-existing
"the vendor's RECORD vocabulary" prose, same files, same grep; negative
control: an absent marker, 0 hits). Published bytes move, so `patch`, not
`skip-changeset`.

+'@objectstack/client': patch
+---
+
+`oauth.applications.register`'s docblock says where a plain `name` IS honoured, and that it is not this route
+
+A caller who wants to name an OAuth client reaches for `name`. On the route this
+method posts — the provider's `/oauth2/create-client` — that member is not in
+the body schema and is stripped: driven on a real socket, the call answered
+**201** and the value was absent from the response, from `applications.get`,
+from `applications.list`, and `null` in the `sys_oauth_application` row's `name`
+column. Nothing in the answer says so.
+
+The spelling is not wrong everywhere, which is what made it worth writing down:
+`POST /api/v1/auth/sys-oauth-application/register` — the session-required
+ObjectStack mount behind the Console's *Setup → OAuth Applications* form —
+answered **200** to the same body, mapped `name` onto `client_name`, and set
+that column. That mount is `disposition: 'server-only'` in the auth route ledger
+and objectstack#17210 ruled it stays that way, so no SDK method builds its URL.
+
+The docblock now states both halves where the caller reads them: post
+`client_name` to name a client from here, and `redirect_uris` must arrive
+pre-split — the newline-separated-textarea split is the Console wrapper's, not
+this route's.
+
+Docblock only. No method is added, no request or response type changes, and the
+ledger row is untouched — but the text ships inside `dist/*.d.ts` as editor
+hover, so it is a `patch` rather than a no-publish change.
