feat(background): déclencheur in-app des tâches de fond via MCP idea_run_in_background (BE-1+BE-2)

Ferme la boucle B8 côté surface agent : un agent peut lancer une commande
en tâche de fond depuis l'app, sans dépendance à un déclencheur externe.

- domain : variante OrchestratorCommand::RunInBackground.
- infrastructure : outil MCP idea_run_in_background (déclaration + schéma +
  map_tool_call), tests de mapping et compteur de catalogue.
- application : handler → SpawnBackgroundCommand (owner=requester, WakeOwner).
- app-tauri : câblage .with_spawn_background_command + catalogue MCP 23→24.

Tests verts : domain 452 / application 467 / infrastructure 489 /
app-tauri 236, build --release vert.
