v0.2.2 — Small Android Installer

Aura v0.2.2

This release focuses on making Aura easier to install and safer to publish as a small Android package. The APK no longer carries model weights; first launch lets users choose E2B for a faster start or E4B for higher quality, then runs locally after the model download.

What changed

• Android release packaging now prioritizes arm64-v8a and removes unused x86 native libraries.
• Public APK size is now about 103 MB instead of a multi-GB bundled-model installer.
• README / README.zh-CN / CHANGELOG now match the current first-run model download flow.
• macOS test shell now includes the local LiteRT bridge, and the iOS simulator build script has a fallback for current Xcode command parsing.

Note: no Android device or running simulator was available on this machine at release time, so device-click smoke testing was not performed in this pass.
