v0.3.0

• Screenshots in the README and on the website (from sandesh demo).

• Ticks: ✓ sent, ✓✓ delivered and blue ✓✓ read beside your WhatsApp
  messages, from the phone's receipts and its history.

• Paste a screenshot: Ctrl+v while typing attaches a copied image;
  files about to go show as small previews above the box.

• Pictures full size: Space (or Enter) on a picked photo or GIF
  fills the screen; h/l go through the chat's pictures.

• Compact chat list: two rows per chat instead of a box, so about twice
  as many fit; chat_list = "cards" brings the boxes back.

• The undo window where you look: a message counting down to send, or
  waiting for approval, shows under the conversation; z cancels the open
  chat's own first.

• Clearer: the unread count sits on Unread, not All; the list title says
  "chats"; a one-to-one chat shows the number, not "You, Amma · 2 people";
  the hint under the message box, which repeated the key bar, is gone.

• Photos, GIFs and files on WhatsApp: they show in the conversation (on
  kitty as real pictures, in tmux popups too, and GIFs play; elsewhere as
  coloured blocks; the images option chooses), and Ctrl+o while typing
  or U sends them, with the text as the first file's caption.

• Link WhatsApp from its tab: L shows the QR code, P a phone code,
  and a bar follows the sync, with no separate terminal.

• send_policy = "trust" and ask_first: agents send without asking
  unless you told them to ask, after an undo window with a notification
  that can cancel it (ADR 6). The approval screen is redesigned.

• The chat box grows: long messages wrap and the box gets taller, and
  Enter sends and keeps you typing. The active tab is a filled pill in its
  own colour.

• Fixed: WhatsApp names and mentions showing as numbers; @ and the AI
  keys not finding claude or sandesh from a tmux popup.

• WhatsApp: sandesh whatsapp link links your WhatsApp as a device
  (QR code, or --phone for a code to type on the phone), and its chats
  become a third tab (Tab: Mail → Chat → WhatsApp) with unread counts in
  sandesh status and the tmux segment, notifications, read receipts and
  quoted replies. sandesh whatsapp list|read|send|unlink on the command
  line, whatsapp_chats, whatsapp_read and whatsapp_send for agents.
  Every send goes through the outbox; an agent's always waits for you, and
  WhatsApp sends are capped at whatsapp_per_hour (30). Without linking,
  whatsapp send opens WhatsApp's click-to-chat page with the text typed
  in instead. Linking isn't allowed by WhatsApp's terms
  (see the README's WhatsApp section and ADR 5).

• HTML mail, for tables and the like: mail_send and mail_draft take
  an optional html (and sandesh mail send an --html FILE). It goes
  out beside the plain text as multipart/alternative, so mail apps show
  the HTML and the plain text is still there for those that don't; a reply
  quotes the thread in the HTML too. Plain text alone can't make a table
  Gmail shows as one.
