Retrieval-aware embeddings

Query/document intent is an explicit input_type on the generic rag.embedding@1 request. Concrete instructions remain in the immutable RuntimeProfile; clients never receive model paths or prompt syntax. Qwen3-Embedding-0.6B uses the exact-revision upstream query instruction and an empty document prefix. The instruction source and revision are part of EmbeddingSpace identity.

Changing instruction, pooling, normalization, dimension or another behavior-affecting setting creates a new RuntimeProfile and EmbeddingSpace and requires a separate reindex. The M6 raw profile and space remain immutable.
