Add a copy-to-clipboard button that appears on hover for each code block rendered in the chat interface assistant messages. - Svelte action `codeBlockCopy` injects a button into every `<pre>` element - MutationObserver reattaches buttons as streaming content arrives - Button shows a check icon for 2 seconds after a successful copy - Uses clipboard API with execCommand fallback for non-secure contexts - CSS hides button by default and reveals it on pre:hover https://claude.ai/code/session_01PTA5ao5YQuFAS6a9juLeZW --------- Co-authored-by: Claude <noreply@anthropic.com>
