v1.3.1

This hotfix improves filename handling, localized display details, and release reliability across platforms.

Fixes

• Prevent filename errors for long downloads and Windows-reserved names such as CON and COM1. Names are shortened safely while keeping their file extensions, addressing #29.
• Correct Persian date formatting in affected settings and timezone cases, while preserving Hebrew locale formatting.
• Fix remaining light-theme overlay and contrast details reported with the broader appearance and localization work in #31.

Improvements

• Make Linux AppImage packaging more reliable and avoid compiling the same Rust release binary twice.
• Strengthen cross-platform release checks so Windows and Linux test builds handle macOS-only code correctly.

Compatibility

• Firelink Companion 2.1.0 remains the current compatible extension. No extension update is required for this hotfix; use the latest Companion release.
