Project skeleton: Gradle 9.4.1 wrapper, AGP 9.2.1, Compose, manifest with reminder permission set

Milestone 1 of the build brief. Version catalog pins verified against
Maven Central / Google Maven on 2026-06-10; Kotlin held at 2.3.10 to
match AGP 9.2's bundled KGP (built-in Kotlin) because KSP has no
Kotlin 2.4 release yet. compileSdk 37 (forced by core-ktx 1.19),
targetSdk 35 per brief. allowBackup=false + full dataExtractionRules
opt-out; own encrypted backup comes in milestone 5.
