sqlite-graphrag 1.0.82

//! GAP-005 (v1.0.82): `pending-embeddings` subcommand — high-level batch
//! operations over the `pending_embeddings` queue.
//!
//! ## Subcommands
//! - `pending-embeddings list` — alias of `embedding list`
//! - `pending-embeddings retry-all` — bulk re-queue for retry
//! - `pending-embeddings abandon` — bulk mark abandoned
//!
//! The split between `embedding` and `pending-embeddings` mirrors the GAP-005
//! plan: `embedding` carries per-entry inspection (`status` / `abandon <id>`)
//! while `pending-embeddings` carries batch operations over the queue as a
//! whole. The two share the same `pending_embeddings` table and storage
//! layer.
