feat(probe): sonde enrichie CPU/RAM/disques + recommandations de profils (tâche 4)

- template machine-probe : lscpu Model name + nproc, MemTotal, lsblk disques
- parseProbe étendu (cpuModel/cpuCores/memoryBytes/disks) + buildRecommendations
  (KVM/QEMU → vm_guest_tools) ; tests TDD
- runProbe persiste cpu/mem/disks dans machine_hardware ; /probe renvoie recommendations
- popup Sonde affiche cpu/ram/disks + profils conseillés

tsc 0 · 110 tests · build OK.
