Project restructuring for Sample app

[luhmirin-s]

• Moved "SimFace" into a library sub-module
• Imported the sample app from SimFaceTester repository
• Run several rounds of code prettify on the sample app to make it as simple and clean as possible (might have overdone it a bit)

[Copilot]

Pull request overview

This PR restructures the project into separate Gradle modules (:simq, :simface) and adds a new Compose-based :sample app, while also updating build tooling and CI/publish workflows to target the new module layout.

Changes:

• Split SimFace into its own Android library module (:simface) and adjusted Gradle/CI to build & publish it.
• Added a new :sample Compose + CameraX demo app showcasing face detection, embedding, and matching flows.
• Introduced/ported core SimFace runtime + Android instrumentation tests (embedding, matching, detection, alignment).

Looks good to me and the demo app works well on my phone. Only things worth double-checking are the Gradle issues from the Copilot review and whether the publishing pipeline works smoothly.

[martin-simprints]

Does this import both simface and simq?

[luhmirin-s]

SimQ is added transitively, so this will add both.
