Pre-announcement sweep: a contact channel, a fresh Titles shot

Three of four reviewer nits. The real gap: the Gitea instance takes no
public registrations, so announcement readers had no way to report
anything — the README now offers the author's email and says plainly
why there's no issue tracker yet. The Titles screenshot still showed
the day-three catalog ("123 extracted titles") — replaced with the
clean run's capture (150 reads, shaky-read badges, the add-a-game
panel) and honest alt text. And the Beta classifier gets a comment
recording that it's deliberate alongside the README's "battle-tested":
tested for one person on one platform is exactly what Beta means.

The fourth item (release notes on the v1.0.0 tag) is a Gitea web-UI
task — notes drafted separately for pasting.
