- Replace separate Frontend/Backend versions with single app version
- Version is now a clickable link to the GitHub release page
- Replace stopwatch SVG with actual app logo (favicon.svg)
- Fix update check UX: previous result stays visible during re-check
- Add 1s minimum delay for update check spinner visibility
- Reserve space for update result to prevent modal jumping
- Remove unused i18n keys (frontend/backend)
- Update release-manager docs with version link info
Document that both backend/package.json and frontend/package.json
must be updated before tagging a release, since the About modal
reads versions from these files.
Create dedicated GitHub Copilot agent for release management with
4 tasks: branch/PR workflow, version determination, release execution,
and release notes writing.
Move release-specific instructions (workflow, release notes format,
breaking changes) from copilot-instructions.md to the agent file
to keep concerns separated.
