feat(m15): nvidia-smi snapshot + display logs + inventory in reports — 0.32.0

Expand diagnostic/report collection (all stored per-diagnostic, in the Report zip;
logs also fed to the AI on "Explain"):
- syslogs: nvidia-smi -q snapshot (driver/throttle/clocks/power/temps/PCIe/ECC/
  retired pages) + display-server log auto-detected — Xorg.0.log on X11, or the
  compositor user-journal slice (gnome-shell/kwin/sway/gamescope) on Wayland.
- diagstore: include the full M5 inventory (inventory.txt + .json) — invaluable
  for larger/shared debugging. inventory.collect() degrades gracefully (no root
  prompt). Best-effort throughout.
- Tests for nvidia/display + inventory in store; docs (M15/SPEC).

-  `ai/` record of every AI interaction: exact data sent, model, reply). **"Report"** zips one
-  into `DATA_DIR/reports/` (GUI button on the diagnostic dialog; CLI `rigdoctor bundle`). All
