docs: reconcile compileSdk 37 references across docs + gradle

The project moved to compileSdk 37 (206d182) but the docs and the
android.suppressUnsupportedCompileSdk flags still said 36. Align them:
CLAUDE.md "Compile SDK 36" → 37, docs/spec.md adds the Compile SDK line,
and gradle.properties + quest/gradle.properties suppress flags → 37.
