程序员阿江(Relakkes) 86cd2b8d18 Keep desktop UI icon previews aligned with the packaged app icon
The desktop UI was still rendering the old JPG preview asset, so the empty
state, sidebar, and settings pages continued to show the legacy glow-backed
image even after the packaged app icon was corrected. This switches those UI
surfaces to a PNG generated from the current canonical app icon source so the
in-app preview matches the shipped icon treatment.

Constraint: The desktop UI still referenced a legacy JPG asset with the removed outer glow background
Constraint: There are unrelated staged changes in the worktree, so this commit must stay file-scoped
Rejected: Leave the UI on the JPG asset | keeps showing a stale icon treatment after the packaging fix
Rejected: Revert the packaged icon to match the old JPG | would reintroduce the original square-background problem
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep desktop/public/app-icon.png in sync with desktop/src-tauri/app-icon.svg when the app icon changes
Tested: desktop bun run lint; desktop bun run test
Not-tested: Manual visual pass in the running desktop app after rebuilding the frontend bundle
