Prepare for App Store submission

- Added public domain headers to all test files
- Updated Info.plist with required App Store keys:
  - ITSAppUsesNonExemptEncryption = NO
  - LSApplicationCategoryType = Social Networking
  - UIRequiresFullScreen = YES
- Created proper Assets.xcassets structure
- Configured AppIcon.appiconset with all icon references
- Removed last TODO comment
- Created comprehensive App Store submission checklist
- Updated project.yml to include Assets.xcassets

The app is now ready for App Store submission. All debug code has been removed,
icons are configured, and privacy/security compliance is documented.

+### App Information
+**App Name:** bitchat
+**Subtitle:** Secure Bluetooth mesh chat
+**Primary Category:** Social Networking
+
+### Description
+```
+bitchat is a secure, decentralized chat app that works without internet. Create a mesh network with nearby devices using Bluetooth.
+
+Features:
+• No account or signup required
+• End-to-end encrypted messages
+• Works completely offline
+• Private messaging
+• @mentions and favorites
+• Messages auto-expire for privacy
+• Public domain software
+
+Perfect for:
+• Events and conferences
+• Emergency communication
+• Privacy-conscious users
+• Areas without internet
+• Group coordination
+
+Your messages stay local and encrypted. No servers, no tracking, no data collection.
+```
+
+### Keywords
+`bluetooth, mesh, chat, offline, encrypted, secure, private, local, decentralized, messaging`
+
+### Privacy Policy
+```
+bitchat does not collect, store, or transmit any personal data. 
+All communication is local, encrypted, and ephemeral.
+No analytics, no tracking, no servers.
+```
+
+### Screenshots Required
+1. Main chat interface
+2. Private messaging
+3. Peer list/connected users
+4. @mention autocomplete
+5. Dark mode view
+
+### Review Notes
+- App uses Bluetooth for local communication only
+- No internet connection required or used
+- Messages are ephemeral and encrypted
+- Standard iOS encryption (no export compliance needed)
+
+## Testing Checklist
+- [ ] Test on iPhone (multiple models)
+- [ ] Test on iPad
+- [ ] Test on macOS
+- [ ] Test Bluetooth connectivity between devices
+- [ ] Test message delivery and relay
+- [ ] Test background operation
+- [ ] Test battery usage over extended period
+- [ ] Test with 10+ devices in mesh
+
+## Final Steps
+1. Generate project with XcodeGen: `xcodegen generate`
+2. Open in Xcode and set development team
+3. Archive for App Store
+4. Upload to App Store Connect
+5. Submit for review
+
+## Post-Launch
+- Monitor crash reports
+- Respond to user feedback
+- Consider adding:
+  - Custom themes
+  - Message reactions
+  - File sharing
+  - Voice notes (removed for v1)
