AliOsm/chromable

Provides declarative embedding management for ActiveRecord models with automatic sync via `after_save`/`after_destroy` callbacks, supporting custom embedder functions and metadata filtering. The gem wraps the `chroma-db` client to handle vector storage separately from relational data, reducing memory footprint by optionally excluding document text from ChromaDB. Exposes query methods that embed input text on-the-fly and return matched records, plus instance-level neighbors lookup for semantic similarity searches.
