* fix: Use visibility:hidden for mermaid rendering element
Instead of positioning the temporary render element offscreen at
-9999px, use visibility:hidden with position:fixed so the browser
computes correct bounding boxes for SVG elements. Offscreen elements
can produce incorrect getBBox() results, leading to wrong viewBox
dimensions and diagrams rendering too big or too small.

* Add session storage for generated diagrams to reduce relayout
* fix: Use LRU eviction for mermaid sessionStorage cache
Track access order via a dedicated LRU index key so the cache evicts
least-recently-used entries rather than arbitrary ones.
