Scaffold Android project per BRIEF.md
Single-module Kotlin/Compose app with manual DI container. Pure-Kotlin
measurement math (orientation mapping, two-sample per-mode calibration,
EMA smoothing, lock hysteresis, display deadband) fully unit-tested.
Sensor fallback: game rotation vector -> gravity -> low-passed
accelerometer. Live Level (manual Surface|Edge) and Angle (hold-to-zero)
scaffolds; Ruler/Tools placeholders; stub Pro entitlement.
