Add a Managed Runtime Provider

Add one provider through the repository's runtime-provider contract. Keep generic orchestration independent of provider implementations and provider names.

Confirm Product Scope

Apply the product scope gate in AGENTS.md before implementation or approval. Require an accepted issue or accepted design decision that defines ownership, lifecycle, compatibility, security, and validation. A valid bundle or passing test does not establish a supported surface.

Keep the portable experimental profile independent. Do not change portable selection, lifecycle, or compatibility behavior as part of a native managed-provider change.
