Point the config at 0.2.0, ahead of the tag

The tag stays the single source of truth — ci-set-version.sh rewrites
this key on a tag build and ci-android-version-code.sh derives the
versionCode from it. Committing the same values keeps a local or
sideloaded build from reporting 0.1.0, and keeps the checked-in number
greppable and honest between releases.

1000 + major*10000 + minor*100 + patch puts 0.2.0 at 1200, which is what
CI will compute for v0.2.0. The workspace Cargo.toml is deliberately
left alone: editing it invalidates Cargo.lock and breaks every --locked
build in the same run, to change a number that appears nowhere but the
binary's own metadata.
