Module embedding 

Embedding provider trait and vector utilities.

Defines the EmbeddingProvider trait that all embedding backends implement, plus pure helper functions for vector serialization and similarity computation.

Concrete provider implementations (OpenAI, Ollama, fastembed, tract) live in the context-harness app crate.

Traits

Functions

blob_to_vec
