Hello gains model + modes; Job gains mode. Dispatch routes per connection
capability: article jobs only to article-capable connections and only
while a page is mostly pending; titles/chunks go as markdown (whole
fragment, hybrid-neighbor contexts) or segments jobs. Validation skip
list is now (lang, key, mode). align_article decomposes a whole-article
result into per-chunk stores: non-translatable blocks (fences, HTML,
containers) are verbatim anchors, regions between anchors pair
positionally, mismatched regions and blocks with altered link
destinations/placeholders stay pending.
Verified offline against /tmp/llmtrial outputs: qwen3.8:27b runs pair
105/105 and 43/43 blocks; qwen3:30b-instruct's translated code comments,
qwen3-next's degenerate runs and the structurally broken seedx trial
files (a dropped ::: fence) are all rejected.
