New app: motd

This submission is from the original MOTD author.

Required

• The app complies with the inclusion criteria
• The original app author is submitting this inclusion
• No related fdroiddata or [RFP](https://gitlab.com/fdroid/ rfp/issues) issue was found
• Builds with fdroid build and all pipelines pass
• The upstream issue tracker and author information provide contact paths

Strongly Recommended

• The upstream repository contains Fastlane metadata for the description, graphics, and changelog
• Releases are tagged and automatic updates are enabled

Suggested

• External repositories are pinned as srclibs because the MOTD release build verifies exact sing-box, Android submodule, and gomobile commits
• Reproducible Builds are enabled using the upstream v0.10.7 APK and pinned signing certificate; the F- Droid rebuild matches the supplied reference binary
• MOTD currently ships one arm64-v8a APK rather than a universal or multi-APK build
