Feed: cached posts paint at once, never a spinner over them; the chat home prefetches the feed.

The boot gate hid everything, cached posts included, until the opening
page's faces and pictures had decoded — seconds of spinner on a feed we
already held. Cached rows now paint immediately as they are and take their
prepared presentation once the warm-up lands (the container carries
data-booting meanwhile). The relay fetch starts at once instead of after
the warm-up; arrivals still wait at the door. Opening the chat home warms
and refreshes the current feed, so the Feed tap opens on the latest posts.
