Migrating from Tauri to Electron: Performance Comparison

I recently did this (with Opus 5) for a private project and was content with the result. There were 2-3 minor things I had to fix afterwards, but overall it went well.

I can now finally (and easily!) build AppImages that work on multiple Linux distros. I still have to use XWayland (like I did with Tauri anyhow) due to an upstream Chromium bug w/ global hotkeys, but it should land soonish, so then I'll be using native Wayland too.

As a bonus, it also fixed a drag 'n' drop issue I was unable to work around on Tauri (scrolling viewport with mousewheel while dragging an object), plus scrolling perf is night and day.
