1.39.2 — smooth again, and the hourglass no longer makes VS Code flicker

• Smooth again, and still light. In 1.39.1 the characters’ small motions moved in visible steps. They are smooth again: one clock moves them all together 25 times a second, instead of the browser redrawing the page 60 times a second, so the call stays light in VS Code.
• The hourglass no longer makes VS Code flicker. The turning ⌛ of an agent that waits on others (the lead while its sub-agents work) and the slow drift of the backgrounds were left out of 1.39.1, and kept the page redrawing 60 times a second. They now move with the rest.
