Bump version to 0.0.16

Needed to deploy over the CI-installed build on device: CI derives
versionCode as 1000 + major*10000 + minor*100 + patch, so the field is
already at 1000, while a local `tauri android build` writes the raw
patch number (15) and is rejected as a downgrade.

Cargo.toml is versioned independently (0.1.0) and is left alone.

Note: local builds still emit the raw code (16) - only CI applies the
1000+ formula, so deploying to a device with a CI build installed needs
gen/android/app/tauri.properties patched after Tauri regenerates it.
