🤖 Automated code review

Fresh full static review completed for exact three-dot range b2460b0...2488bf2. The release version is synchronized across all changed package, Tauri, Rust manifest, plugin, CLI, and lockfile declarations, and the changelog entry is consistent with the release boundary and previously merged work. No publishable findings were identified. Final self-check covered every changed human-visible release flow; accessibility; i18n/localization completeness; navigation and consent guards; async, error, never-completes, lifecycle, and race behavior; test honesty; design-system and project rules; duplicate/overlapping findings; and concrete evidence plus user effect for blocking severity. Runtime UX, accessibility, localization catalogs, navigation, consent, and async/lifecycle behavior are not modified by this metadata-only PR. Supplied CI evidence was inspected: Clean-room frozen install and DCO Check succeeded, while frontend checks and macOS, Windows, and Linux Tauri checks were in progress when captured; required checks still govern merge readiness. Recommendation: APPROVE.

Deterministic publication result: 0 blocking and 0 non-blocking finding(s) publishable; 0 duplicate(s) suppressed.

Pending checks: 2 check(s) are not complete.

This approval reflects the completed code review only; merge readiness remains governed by the repository's required checks.
