Having all the syntax cards rendered caused lag when filtering, so this implements virtual scrolling (only the visible items + a few are rendered, and this virtual window is updated as the user scrolls). Performance is noticeably faster, esp on dev server.
Also implements sync sidebar scrolling, better jump-to behavior, and highlighting the currently viewed syntax in the sidebar
To achieve this, I pulled a lot of code into SyntaxDisplayManager, which now collates all the filter info and handles the all the display and scroll logic
I utilized clause a lot for initial development due to my limited domain knowledge, though all code is now either rewritten or verified. All comments are my own. Please double check the design/details.
