Subject: feat: double-click tab to rename (PUT /conversations/:id/title)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Double-click a tab's title to enter inline edit mode. Enter or click
away (blur) saves; Escape cancels. The rename is optimistic — the
local tab updates immediately and PUT /title fires in the background.

683 tests green.
