fix(indexer): use upsert_chunks return value for chunk count

Previously total_chunks counted from process_file return (num_chunks)
which could differ from actual stored count if upsert silently failed.
Now using stored count returned by upsert_chunks.

Also fixes cli._index to skip progress yields when building result.
