release: git-arboretum 3.3.0 (« Démarrer le projet » : lancement multi-terminaux), vscode 0.4.0, desktop 0.1.3

« Démarrer le projet » : un repo définit une fois ses commandes de démarrage
(serveur de dev, API, base de données), un clic ouvre un terminal PTY par
commande dans le dock IDE.

Serveur (additif, PROTOCOL_VERSION inchangé) :
- LaunchCommand[] persistées sur repos.launch_commands (migration 13) ; champ additif SessionSummary.launchRunId.
- POST /repos/:id/launch : résolution du worktree côté serveur, cwd de commande borné (anti-traversal), commandIds outrepasse enabled.
- GET /repos/:id/launch/detect : détection package.json / Procfile / docker-compose.
- Shell de login interactif ($SHELL -l -i, charge le PATH nvm/asdf) + auto-type de la commande ; le shell survit à la commande (échec visible).

Web : LaunchProjectModal + actions (ProjectTreeNode, SessionsPanel, CommandPalette), stores sessions/worktrees, i18n EN/FR.

Alignement du reste du projet :
- Extension VS Code 0.4.0 : commande Start Project (repo/worktree), Stop Launch, badge « launch » dans l'arbre, méthode REST startLaunch.
- Site vitrine : 16e feature card (Rocket) + section showcase « Start the project » (mockup fidèle au modal), i18n EN/FR.
- Documentation : README (EN + FR), help-content (EN + FR), CHANGELOGs server + vscode.

Vérifié : 430 tests, typecheck, build (web + site + vscode), acceptance-p13 ALL GREEN, VSIX packagé, garde anti-tirets, vérif visuelle du site (thèmes clair et sombre).
