infinilabs/analysis-ik ? reverse-engineered prompt

Build me an Elasticsearch and OpenSearch plugin that adds Chinese text analysis with the IK analyzer, so I can index and search Chinese content more naturally. I want the plugin to support both ik_max_word and ik_smart, work with highlighting, and let me use a custom dictionary and stop words file from the config folder. Please make it so the dictionary can also be loaded from a URL and refreshed without restarting the cluster, as long as the server sends the right headers. If you need to, look up the current Elasticsearch and OpenSearch plugin docs online so the install and packaging steps are correct for recent versions. I’d like the result to be something I can build, install, and test locally with a simple example index and search request.
