feat(domain,app,infra): injection « État du projet » + outils MCP workstate (LS4)

Clôt le cold-start de coordination du programme live-state :
- domain : WorkStatus::parse/label, commands ReadWorkState/SetWorkState
  (request status/intent/progress/lastDelegation), erreur UnknownWorkStatus + validate.
- application : section bornée « # État du projet » injectée au lancement
  (port LiveStateLeanProvider, InjectedLiveRow, LIVE_STATE_INJECT_MAX, resolve_live_state) ;
  LiveStateReadProvider + read_workstate/set_workstate câblés au dispatch.
- infrastructure : 2 ToolDef idea_workstate_read / idea_workstate_set (mapping,
  tool_returns_reply), compteur d'outils MCP 12→14.
- app-tauri : providers câblés, garde du nombre d'outils 12→14.
- tests (QA, verts) : domain/orchestrator, application lifecycle + orchestrator_service,
  infrastructure mcp_server, app-tauri state.
