release: prepare Desktop 0.13.16

Package approved bilingual notes for history upgrade reclamation, continuous
Supervisor reviews, and clearer review/activity layouts. Align feature lists
and retain published notes. Agent remains 0.13.4; no schema bump or LoongArch.

Update two stale layout assertions to match removed repetitive copy.
Record candidate validation and the isolated Mermaid rerun without claiming
a clean full-suite result. Require main CI and production build before tagging.
