build.rs now re-runs when the commit changes (cargo:rerun-if-changed on .git/HEAD + the branch ref) so GIT_HASH never goes stale, and appends -dirty when tracked code (frontend, src-tauri/src, build.rs) is uncommitted. Lets a distributed APK be pinned to an exact source commit for regression tracking. README documents versionName 0.1.NNN + hash traceability. Decision at b4fdc824144.
