Expand description

Embeds a single text via the given backend. Used by embed_with_fallback and exposed to allow direct one-shot selection without a chain. Embeds a single text via the given backend. Used by embed_with_fallback and exposed to allow direct one-shot selection without a chain.

BUG-003 / v1.0.85: returns (Vec<f32>, LlmBackendKind). The second element reports the backend that ACTUALLY executed the embedding, not the chain position requested by the caller, so envelope.backend_invoked shows the operator the truth.

The tuple mattered more when the chain could substitute one subprocess backend for another; v1.2.0 reduced LlmBackendKind to OpenRouter and None, so the two now only differ when OpenRouter is unreachable and the caller falls through to None.
