The Claude web UI has changed its DOM structure since the original selectors were written. User messages are now found via [data-testid="user-message"] and assistant messages via div.standard-markdown. Code language detection updated to use language-* classes on <code> elements. Also adds ESLint config and fixes lint warnings (var -> const/let).

There was a problem hiding this comment.
dist/json.min.js worked for me, my gemma4:e4b instance analyzed the code as being functionally identically except for the updated DOM selectors.

The previous selectors (
div.font-claude-message,div.font-user-message,div.flex-1.flex.flex-col.gap-3.px-4) no longer exist in the Claude UI, causing aTypeError: Cannot read properties of nullwhen running the exported scripts.Test plan
