v2.3.0

Added

• Pluggable embedding provider (opt-in). Point iai at your own local embedding model over a loopback HTTP service instead of the built-in English BGE, enabling multilingual or domain-specific recall. The native BGE stays the zero-config default with unchanged weight and speed; the provider is strictly opt-in, loopback-only (127.0.0.1), with strict response validation and a resumable, zero-failure re-embedding migration.
