Bump to v0.8.0 — polish, portability, discovery

Profile banner polish (hero height, click-to-lightbox, avatar overlap),
data export (bookmarks/follows/relays as JSON), relay recommendations
(discover from follows' NIP-65 lists), reading list tracking (read/unread
on bookmarked articles with sidebar badge), trending hashtags (clickable
pills on search idle screen). Updated CLAUDE.md and release notes.
