Support AAB

[sharifhh]

Note

Add AAB build support and propagate build type through artifact discovery, caching, naming, and messaging.

• Action (action.yml):
  • Add aab input to toggle Android App Bundle builds.
  • Set BUILD_TYPE env (aab/apk) and pass --aab to rock build:android when enabled.
  • Generalize artifact discovery to pick *.aab or *.apk accordingly.
  • Include build type in cache traits and artifact naming for listing, uploading, and re-sign flows.
  • Rename APK-specific steps/messages to generic “Binary”; update PR comment title accordingly.
• Docs (README.md):
  • Document aab usage and input in examples and Inputs table.

Bug: Artifact cache doesn't distinguish AAB from APK

The ARTIFACT_TRAITS used for caching only includes variant and optionally PR number, but doesn't include the aab input. This causes the system to return a cached APK when an AAB is requested (or vice versa) if they share the same variant, since the artifact lookup can't distinguish between the two build types.

Thanks for the contribution! Removing keystore-store-file is a breaking change that's not necessary to support AAB signing. I don't think we need any of these "less keystone variables" stuff in this PR, please remove it.
