* fix(editor): pause expensive decorations during fast scroll bursts
Add a scrollThrottle plugin that flags the editor with a .cm-scrolling
class while the wheel is moving. While the flag is up the sticky-scroll
header and indent guides are hidden via theme CSS, and their view
plugins skip per-viewport re-measures/rebuilds; a trailing scrollSettled
effect re-runs them once the wheel rests for 140ms. This keeps fast
mouse-wheel scrolling from painting rows of stale decorations over
freshly rendered code.

* fix(editor): keep decorations painted during scroll bursts
The scroll throttle hid the sticky header and indent guides entirely while
scrolling, which flickered on every burst - and the sticky header is exactly
what you want to see while scrolling. Drop the display/background hiding from
the theme and keep the previous paint instead: the plugins skip re-measuring
during a burst and catch up once on the trailing scrollSettled update.
* fix(editor): throttle the first scroll event and queued sticky measurements
