AtomChat

Added: a public-feed filter button next to the header back arrow, cycling all / system-only / players-only (icon changes per state, accented while filtering). View-only — unread badges and previews still count every message. Fixed: bare own names on relay servers (NCR-style), sender name rows inheriting server underlines and click events, anti-spam merging with no time window (and merging dropping text selections and jump highlights), empty Ctrl+C after scrolling during a selection, and emoji split in half by surrogate pairs. Changed: layout cache for message wrapping, making long-list scrolling and panel opening noticeably smoother.
