release: git-arboretum 3.7.0 (fin de l'écran noir, colonnes de terminaux, git scopé), desktop 0.2.4

Le desktop 0.2.4 embarque le daemon 3.7.0 et livre aussi les garde-fous de
démarrage déjà sur main (dialogue d'échec, reprise d'un daemon orphelin,
redémarrage après mise à jour installée à chaud).

 Notable changes to `@johanleroy/git-arboretum` (the Arboretum daemon). The VS Code
 extension keeps its own changelog in `packages/vscode/CHANGELOG.md`.
 
+## 3.7.0
+
+Terminals stop going black, and they now sit side by side. Files and commits follow the terminal you
+are actually looking at. Fully additive, no protocol version bump.
+
+- **A terminal could stay completely black while its session was alive and running.** The attach
+  replay is a binary frame, but a client only learns its channel number from the `attached` message.
+  The server sent the replay *first*, so every client dropped it on an unknown channel: nothing was
+  painted, and a resting TUI (Claude at its prompt) never emits anything on its own. `attached` is now
+  sent before the replay, which fixes the web app, the desktop app and the VS Code extension at once.
+  A resize on attach used to hide the bug by triggering a repaint through SIGWINCH, which is why it
+  looked intermittent.
+- **Screen-less attachments.** `attach` accepts an optional `screen` flag (default `true`). With
+  `screen: false`, a client that only wants to answer a dialog no longer takes control of the session,
+  no longer forces its own dimensions onto the PTY (which used to freeze the real terminal's geometry)
+  and no longer receives the output stream just to throw it away.
+- **The reason a session died is now visible in the terminal**: a last line, `[arboretum] claude
+  exited with code 1`, is written to the stream before clients are detached. A process that died at
+  spawn time used to leave nothing but an empty screen.
+- **A stale Claude CLI path is re-resolved.** The resolved binary was cached for the lifetime of the
+  daemon; after an nvm or asdf switch it pointed at a file that no longer existed, and the PTY died
+  without a single byte of output.
+- **Terminal columns.** The dock holds up to three resizable columns, each with its own tabs. Alt+click
+  a session (tree, panels, attention list) or use the tab button to open it beside the current one.
+  Keystrokes always go to the focused column. The dock's height ceiling now follows the viewport
+  instead of a fixed 640 px, and opening the dock gives it a usable height.
+- **Changes are scoped to the focused terminal.** The Changes view shows the worktree of the terminal
+  you are working in, or every repo of its group for a group session, with a one-click "show every
+  project" toggle. The Git index in the sidebar stays global on purpose: it is the way out of a narrow
+  scope. The activity-bar badge stays global too: it exists to surface work you are *not* looking at.
