chore: add systemd units for Smart IDE core services

**Motivations:**
- Manage ia-dev-gateway, tools-bridge and orchestrator as user services.
- Provide a repeatable install path aligned with existing systemd patterns.

**Root causes:**
- N/A

**Correctifs:**
- N/A

**Evolutions:**
- Add systemd user unit templates for ia-dev-gateway, smart-ide-tools-bridge and smart-ide-orchestrator.
- Add an install script and document it in docs/repo/systemd-units.md.

**Pages affectées:**
- N/A

+Unités **user** pour :

+- `ia-dev-gateway` (catalogue agents, runs, SSE)

+Installation :

+systemctl --user start ia-dev-gateway smart-ide-tools-bridge smart-ide-orchestrator
+systemctl --user status ia-dev-gateway smart-ide-tools-bridge smart-ide-orchestrator
+```
+
 ## Linger (session fermée)
 
 Les timers **user** ne tournent en général que lorsqu’une session utilisateur systemd est active. Pour exécuter les timers après déconnexion graphique complète, activer le **linger** pour l’utilisateur : `loginctl enable-linger <user>` (décision d’administration machine).
