Function embed_chunks_inline 

pub async fn embed_chunks_inline(
    config: &Config,
    pool: &SqlitePool,
    chunks: &[Chunk],
) -> (u64, u64)

Embed chunks during sync (inline). Non-fatal on failure.

Called by crate::ingest::run_sync after chunking each document. Checks each chunk for existing, up-to-date embeddings before calling the provider, avoiding redundant API calls.

Returns

A tuple (embedded, pending):

• embedded — number of chunks successfully embedded (or already up-to-date)
• pending — number of chunks that failed to embed
