Verify what upstream Cinny 4.12.x already renders for <pre><code> (react-custom-html-parser code branch + ReactPrism): there may be a copy affordance already.
Scope
Hover/focus-visible Copy icon button in the top-right of a code block (copies the raw text, not highlighted HTML); "Copied" state for 1.5 s.
Wrap toggle next to it for long lines (default: no wrap, horizontal scroll — current behaviour). Remember the wrap choice per session only.
Must not change the existing markdown/HTML output, message layout widths, or the Lotus Terminal syntax theme; snapshot the current rendering before/after (headless screenshot).

Verified upstream first: every code block already has the Copy chip with a 'Copied' state. Added the missing half in 2a0c4091: a Wrap chip that switches long lines to pre-wrap (default stays no-wrap + horizontal scroll), remembered for the session only. Output, widths and the syntax theme untouched. Verified headless: scrollWidth 1016 → 612 px with wrapping on.
