QVAC-23467 doc: point Bare consumers at @qvac/inference

[opaninakuffo]

🎯 What problem does this PR solve?

• @qvac/bare-sdk is discontinued after 0.18.1. Docs, READMEs, and the Bare plugin-registration error still send in-process Bare users to that package.
• There will not be a 0.19.0 of @qvac/bare-sdk. Those users should assemble plugins on @qvac/inference.

📝 How does it solve it?

• Rewrite the @qvac/bare-sdk README as a deprecation + migrate-to-inference page.
• Point architecture docs, repository layout, website SDK/plugin pages, and the @qvac/sdk / @qvac/inference READMEs at inference.
• Update WORKER_PLUGINS_NOT_REGISTERED copy to recommend @qvac/inference.

Pipeline / package deletion is a follow-up: #4019.

🧪 How was it tested?

• Copy review of the deprecation wording (last release 0.18.1; no 0.19 of this package).
• No runtime tests. Historical changelogs and release-notes MDX left unchanged.

Thanks. I think we should reshuffle the docs a bit to clarify three things:

• SDK no longer runs on Bare (it never did as it is actually, users needed to register plugins etc.).
• People who want to run QVAC on Bare should use inference.
• Bare SDK is deprecated.

We should do it as current fact as it is, instead of narrating it as journey ("SDK once supported Bare, but no longer, use Inference...").
