standalone-indexer (h24 line): hash image blocks from tokens only - #44
Merged

Conversation
vLLM attaches each image's identifier to a stored block in extra_keys, and the shared ZMQ normalizer mixed it into the block's tokens hash. The standalone indexer's queriers hash plain token ids: deepapi's probe does, and so do the engine local-indexer TreeDumps served by /kv_recover. Every query therefore stopped matching at a conversation's first image block. Measured on frank/DeepSeek-V4.1-Flash with a live ZMQ capture: for chains whose first image fell in the window, a plain probe matched exactly up to the image block (217, 1098, 1569, 358 blocks) while an image-aware probe matched the whole chain (589, 2432, 3054, 6450). The indexer predicted 0.77 vs actual 0.96 on prompts over 500k tokens. Add ZmqEventNormalizer::with_plain_mm_hashing() and use it in the standalone listener. The library default is unchanged for Dynamo's own router, which queries with image info. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Cherry-pick of #43 onto the h24 line. The h24 flavor takes its tokens hashes from the same listener normalizer, so it had the same break at a conversation's first image block.
Validation: cargo test -p dynamo-kv-router --features kube-discovery --lib: 615 passed.
Stacked on #42.
