 - [x] **`busy_timeout` on the email db** (done 2026-07-24, `9527e0b`). API + email sidecar share

+- [ ] **Multiple views in the Email screen (tabs).** The screen grows beyond the current mailbox into
+      several switchable views:
+  - [ ] **Sender/domain management view.** Left panel: controls to group mail **by sender** or **by
+        domain** (room for more grouping axes later). From a group, run bulk actions on that
+        sender/domain: **unsubscribe + mark irrelevant**, **delete all mail** from it, **block/ignore
+        future incoming**, etc. Think "inbox cleanup / triage" — operate on a whole sender at once.
+        - Needs: aggregate query (count/size per sender + per domain), a block/ignore list the
+          sync/IDLE path honors on incoming, an unsubscribe action (List-Unsubscribe header / link),
+          and bulk delete over a sender/domain.
+  - [ ] **Chat view.** The existing AI email-assistant flow — likely stays roughly as-is, just lives
+        as one of the tabs (main view).
+  - Open question: tabs vs. some other view switcher; which view is default.
