docs(vision): mark shipped Theme A/B/C; refresh PROPOSED

VISION was still listing Firmware/Fingerprint/doctor/rebuild as open
work after they shipped. Sync ✓ rows + rewrite suggested agent slices.
PROPOSED: post-install hardware hints; neon-glass finish-or-quarantine.

Verified: V0 (docs/backlog only). Queue remains #76 [blocked:hw] only.

+  (a) `fwupdmgr` on PATH → “System › Firmware to check LVFS updates”;
+  (b) `fprintd-list` on PATH → “System › Fingerprint to enroll”.
+  One-shot markers in `settings.*` (same in-checkout discipline as
