jmiba/zotero-redisearch-rag: 0.9.25

Improve provider rate-limit handling across chat and indexing workflows: detect common 429 / quota-exceeded failures more reliably, show explicit retry messages for chat provider limits and embedding provider limits, stop treating embedding rate limits as generic provider failures during imports, reindexing, and chat-triggered rebuilds. Tighten RAG query typing by introducing a dedicated final-payload type for streamed chat responses. Harden Zotero item and PDF attachment helpers: normalize object access through safe record coercion instead of loose unknown-property reads, validate PDF attachment keys more strictly before use, keep citekey, short-title, creator-name, and attachment-path extraction logic working against more heterogeneous payload shapes.
