Docling guesses a DocumentStream's format from its first bytes before
considering the extension, so markdown/HTML content starting with a binary
magic signature ("BM" = BMP, "ID3" = MP3) was routed to an image or audio
backend and fell back to plain-text conversion. Prefix the encoded text
with a newline so the sniff finds nothing and the extension decides.
visualize_chunk re-expanded chunks from scratch to recover their refs,
which could not faithfully reproduce the original merge, scores, and
clip — so a visualization could highlight different pages than the
citation covered. Carry the cited items on Citation.doc_item_refs and
resolve bounding boxes from them directly; re-expansion remains only as
the fallback for callers with no stored context (CLI, inspector). Chat,
inspector, the app endpoint, and the frontend pass the refs through.
A merged search result took its chunk_id from whichever constituent
sorted earliest in the document, while its score was the max across the
group — so the citation's identity could point at a different, less
relevant chunk. Anchor chunk_id and the content/refs fallbacks on the
max-score constituent, clip the budget window around that same chunk so
its evidence is never trimmed away, and narrow page_numbers, doc_item_refs,
and attached image bytes to the items that survive the clip.
When a docling-serve instance crashes or returns 5xx, DoclingServeClient now
retries the request on a different instance (up to max_attempts) and trips a
per-instance circuit breaker so subsequent jobs skip a dead instance until its
cooldown elapses. Reuses the shared CircuitBreaker; adds max_attempts and a
nested circuit_breaker to providers.docling_serve.

Relocate CircuitBreaker from ingester/pollers to haiku/rag/circuit_breaker
so non-ingester callers (docling-serve provider) can reuse it without
depending on the ingester package.
