fix(cirkel): strip 'RE: <url>' quote prefix from boost card titles
A boosted plain Mastodon post with no Klonkt title fell back to the raw
text, which for a quote/reply starts with 'RE: <long-url>' (the prefix
Misskey/Akkoma and some reply federation prepend) — ugly noise in the tile
title. tidySnippet() drops a leading 'RE: <url>' and any leading bare URL
so the title shows the actual prose.
- src/routes/circle.js — tidySnippet() applied to the card text snippet
