## Summary
- Replace custom `compareVersions()` with `semver.compare()`
- Replace custom `isSemVer()` with `semver.valid()`
- Remove deprecated version comparison functions from `formatUtil.ts`
- Update all version comparison logic across components and stores
- Fix tests to use semver mocking instead of formatUtil mocking
## Benefits
- **Industry standard**: Uses well-maintained, battle-tested `semver`
package
- **Better reliability**: Handles edge cases more robustly than custom
implementation
- **Consistent behavior**: All version comparisons now use the same
underlying logic
- **Type safety**: Better TypeScript support with proper semver types
Fixes#4787

* [refactor] Move update-related functionality to platform/updates domain
Reorganizes release management, version compatibility, and notification functionality
following Domain-Driven Design principles, mirroring VSCode's architecture pattern.
- Move releaseService.ts to platform/updates/common/
- Move releaseStore.ts to platform/updates/common/
- Move versionCompatibilityStore.ts to platform/updates/common/
- Move useFrontendVersionMismatchWarning.ts to platform/updates/common/
- Move toastStore.ts to platform/updates/common/
- Move ReleaseNotificationToast.vue to platform/updates/components/
- Move WhatsNewPopup.vue to platform/updates/components/
- Update 25+ import paths across codebase and tests
This creates a cohesive "updates" domain containing all functionality related to
software updates, version checking, release notifications, and user communication
about application state changes.
