A Mail surface in the Communication group, distinct from Messenger (chat) and the
work-item Inbox: read app-to-app + email messages (subject + rendered body), reply,
and compose (in-app to a person, or external to an email).
- mail-api.ts: crm.mail.list/history/reply + compose (crm.mail.internal/send), reusing
the messenger directory for the people picker. Live via the AppShell SDK; mock in demo mode.
- mail.tsx: thread list + reader + reply + New-mail composer. HTML bodies render inside a
SANDBOXED iframe (no scripts) — safe against untrusted email HTML.
- Wired into the sidebar (Communication) + dashboard switch.
The existing work-item Inbox stays as the notifier (IIOS's projector already flags new
mail there); this is where you read it. tsc + next build clean.
