Stefan Haller 3cbf40d4ef Reset the scroll to the top at first paint, not when the task starts
When a main view re-renders content different from what it last showed, the
scroll resets to the top. That reset fired synchronously when the task started —
but with the off-screen render the previous content stays displayed until the
swap, so resetting the origin up front scrolled that still-visible content to the
top before the new content replaced it: a distracting jump when switching commits
(or any item) while scrolled down.

Defer the reset to the first paint that reveals the new content, so the previous
content stays at its scroll until the new content takes its place, and then the
new content appears at the top. Swap and reset happen in one hop on the UI
thread, so no draw can land between them and show the new content at the old
scroll. A same-content re-render keeps its scroll. The "loading..." indicator
path also resets the origin now, since it clears the previous content to show the
message and must put it at the top.

The reset moves out of NewTask into the read loop, keying off the flag that
already records whether the render's content is new. NewTask still decides,
from the same command-key comparison as before and under the same lock. It has
to be that flag rather than per-task state, because a task can be stopped and
replaced before it ever paints — a background refresh landing just after the
user clicked a different item, which is the ordering a VS Code terminal
produces, since it delivers the focus-in event (and so the refresh) before the
click. The replacement renders the same content and so sets nothing of its own,
and the click's reset would be lost with the task that owed it.

The manager's onNewKey callback is renamed resetOrigin to match its now-decoupled
timing.
