Initial commit: Foto Dup Finder 1.0.1

An Android duplicate-photo finder. Pure-Kotlin core (SHA-256 + dHash hashing, exact and
perceptual union-find grouping, three sensitivity presets) with MediaStore access, a
persistent SQLite hash index and a tiered ScanEngine behind a Jetpack Compose UI.
No INTERNET permission, no ads, no analytics, no account.

Ships versionCode 2 / versionName 1.0.1, carrying the scan-stall hardening (BoundedCall
breaker) and verified against a 5,363-photo device library. 80 JVM unit tests, lint clean.

Release paperwork is in docs/ (Play checklist, store listing, edge-case testing), the
upload-ready Play graphics and screenshots in store-assets/, and the generators for those
assets in tools/.
