feat: cookie Secure conditionnel + sous-commande d'installation de service

Cookie: routes/auth.ts pose `secure` sur le cookie de session quand la requête
arrive en HTTPS (x-forwarded-proto), sans trustProxy — durcit le cookie derrière
Tailscale Serve sans casser le localhost http.

Install: nouveau cli/install.ts + routeur de sous-commandes dans index.ts
(install/uninstall/status/serve). Service utilisateur systemd (Linux) ou launchd
(macOS), bootstrap du token, --dry-run/--no-enable. Rétrocompat stricte du daemon
par défaut (runDaemon extrait).

Tests: app.e2e (cookie Secure local vs HTTPS) + cli-install (fonctions pures).
203/203 verts, acceptation P1/P4 vertes.

Docs: README.md + README.fr.md (installeur multi-OS, distinction utiliser/cloner,
modèle de sécurité durci).
