Client publishing: TanStack Query artifacts and a dispatchable republish

[ExtraToast]

What to build

The shared client publisher gains the ability to emit TanStack Vue Query artifacts, and the ability to republish a client without waiting for a service release.

Today actions/api-client-publish already generates types, an SDK, Zod schemas and a fetch client via hey-api — only the @tanstack/vue-query plugin is missing. And a new client artifact can only be produced by a full service release, which puts every downstream UI change behind a release plus Renovate's 7-day hold.

This tracker unblocks every UI workstream in the programme.

Acceptance criteria

• A published client exposes query and mutation options behind a dedicated subpath, without forcing TanStack Query on non-Vue consumers
• A client can be regenerated and republished on demand, with no service release
• All three publishing service repos reference one pinned version of the shared workflow
• Verified by pulling the published artifact and reading it — not by a green workflow run
