Summary

Three small build and dependency changes. They came out of a larger Android UI change (#439) but don't depend on it, so they're split out here for easier review. Each commit stands on its own, so feel free to drop any of them.

• build(android): run the Hilt annotation processor for instrumented tests. android/app/build.gradle.kts listed kspTest(libs.dagger.hilt.android.compiler) twice (once under "For instrumentation tests") and never kspAndroidTest. Hilt therefore never generated the test components for androidTest, and every instrumented test failed with a missing TestComponentDataSupplier. The first entry is now kspAndroidTest.
• deps: update rusqlite to 0.41. rusqlite 0.40 → 0.41 and libsqlite3-sys 0.38 → 0.39, which bundles SQLite 3.54.1 and fixes RUSTSEC-2026-0459 (CVE-2026-119375). Exploiting it requires opening a database and WAL file written by someone else, which can't happen with the app's private database, so this isn't urgent, but the update is cheap.
• build(android): optimize the native library for size. Sets opt-level = "z" and codegen-units = 1 for the release-android profile only, so desktop builds are unaffected. The native library is about 70% of the APK, and nothing in it is performance sensitive (it mostly parses and builds small Bluetooth packets). The stripped arm64-v8a library shrinks from 8.3 MB to 4.8 MB, and the arm64-v8a APK from 11.8 MB to 8.3 MB.

Testing

Tested together with #439:

• cargo test -p openscq30-lib --lib --features bundled-dependencies: 228/228 passed
• Android JVM unit tests: 13/13 passed
• Android instrumented tests on an Android 17 emulator (en-US locale): 20/20 passed. Without the first commit, all of them fail during Hilt setup.
• Built and installed the arm64-v8a release-android APK
