huddle 1.2.1 — add a DM contact by short code + About window

Add a contact by short code

You no longer have to read out your full 24-character HD-ID to start a DM.

• Connect codes. Generate a short code (8 chars, e.g. K7M9-Q2X4) valid for 5 minutes. A friend types it into their "add a contact" box and a contact request flies to you — no HD-ID required. The relay holds the ephemeral code→identity map; the code grants nothing on its own (redeeming it only sends you a request you still accept), and it expires fast so it can't be reused to track you.
  • TUI: press G to mint a code; the add-friend box accepts a code, an HD-ID, or a username.
  • GUI: the add-contact dialog has Generate a code to share (with copy + countdown) and accepts a code in its input.
• About window (GUI). Settings → Account → About huddle shows the version and a link to the source: github.com/richer-richard/huddle.

Operators

Redeem requires the relay to be on 1.2.1 (the new CreateConnectToken / RedeemConnectToken handlers). The protocol is backward-compatible — older clients keep working.

All four crates bumped 1.2.0 → 1.2.1.
