Moondrop 0.6.6 — Fullscreen filters and updater verification

Fixes stretched fullscreen filters: search and dropdowns now stay bounded, location and sorting share a row with matching heights, and opened menus use Moondrop's dark colours with consistent spacing.

Unknown-country servers (“Other locations”) now have a question-mark flag in the list, location menu and selected server card.

Fixes the Windows updater helper launch in folders containing non-ASCII characters. The helper uses relative launch paths and preserves its data directory through the child environment.

Adds release checks for the updater using the actual Java runtimes bundled in Windows and both Mac packages. Tests cover verified replacement, restart, rollback, and paths containing spaces and Unicode. Native launcher configuration is checked to ensure it offers full-installer updates; portable editions retain automatic JAR updates after restart.

Windows EXE and macOS DMGs include Java. Choose arm64 for Apple Silicon or x64 for Intel Mac. Installers are unsigned and macOS packages are not notarized. The portable ZIP/JAR requires Java 17 or newer.
