Daak 0.1.0

First release of Daak: end-to-end encrypted file and text sharing on your local network.

None of these files comes from an app store, so each system shows a warning. The steps for each system are in the Install section of the README.

• Android: three APKs, signed with the upload key. Allow Install unknown apps for your browser or file manager. If Play Protect blocks the file, tap More details, then Install anyway.
• macOS: a .dmg, signed with an Apple Development certificate. It is not notarized. On macOS 15 and later, use System Settings > Privacy & Security > Open Anyway. On any version, you can run xattr -dr com.apple.quarantine /Applications/Daak.app.
• iOS: an unsigned .ipa. Sideload it with SideStore, AltStore, or Sideloadly and a free Apple ID. The profile lasts 7 days, so refresh it before then.

Known limit: an iPhone shows as offline on other devices, because iOS blocks the multicast presence beacons. Sends to it still queue and arrive.

Checksums are in release/checklist.md.
