huddle 1.2.3 — message timestamps show real gaps + seconds

• No more "continuous" messages across a quiet gap. The chat used to break only on a new calendar day, so two messages sent minutes (or hours) apart with nobody talking in between ran together as one burst. Now a fresh, timestamped group starts whenever messages are more than ~2 minutes apart, so you can see when time actually passed.
• Seconds in timestamps. Message times now show HH:MM:SS (UTC), matching the logs (already UTC). The desktop app re-shows the sender+time header after a gap; the terminal UI draws a centered time divider.
• Fix: attachment cards stay aligned with message bodies (file-card column width now derives from the message prefix width, one source of truth).

Seeing an old version (e.g. v1.1.3)?

That's a stale install — the version is compiled in, not a bug. Update with cargo install huddle-gui --force / cargo install huddle --force, or git pull && huddle app.

All four crates bumped 1.2.2 → 1.2.3.
