The default of 300 reranker candidates causes 30s+ recall latency for the common case. Most reranker providers are optimized for batches of 50-100 documents. 50 is a safer default that avoids the latency cliff while still providing enough candidates for good recall quality. Operators who need larger batches can set HINDSIGHT_API_RERANKER_MAX_CANDIDATES explicitly. Closes vectorize-io#2554

Summary
The default
reranker_max_candidates=300causes 30s+ recall latency because most reranker providers are optimized for batches of 50-100 documents, not 300. This latency cliff affects all users who don't explicitly configure this value.Changes
