Module embedding 

Embedding generation for text vectorization.

Supports multiple embedding backends:

• Hash-based (default, for testing and offline use)
• OpenAI API (production, high-quality embeddings)

Choosing a Backend

Backend	Quality	Speed	Cost	Offline
Hash	Low	Fast	Free	Yes
OpenAI	High	Medium	Paid	No

Example

use converge_knowledge::embedding::EmbeddingEngine;

// Development/testing: use hash embeddings
let engine = EmbeddingEngine::new(256);

// Production: use OpenAI (reads OPENAI_API_KEY)
let engine = EmbeddingEngine::from_env()?;

// Production with explicit key
let engine = EmbeddingEngine::with_openai("sk-...", None);
