Bump to 0.2.0 — a release at 0.1.0 would have been a downgrade

Found while preparing the release, and it would have quietly defeated the point
of cutting one.

The version does NOT come from the tag. `desktop/packaging/build-version.sh`
reads `desktop/src-tauri/Cargo.toml`, and on `dev` it appends the CI run number
(`0.1.269`) while on a tag or `main` it ships the file's value verbatim — which
was still `0.1.0`.

So tagging today would have published a "release" numbered BELOW every dev build
already out there, and below the 0.1.227 on the operator's phone. The desktop
updater compares semver: an installed build would have read the stable manifest,
seen a version older than its own, and correctly concluded it was already
current. The APK would have installed (versionCode is the run number and keeps
rising) while displaying a version that reads as going backwards.

build-version.sh predicted this in its own comment: "Bumping the minor in
Cargo.toml still wins over any dev build on the old line, which is the ordering
you want: 0.2.0 > 0.1.2932."

Bumped in four places, which is every one that can be read by something:
- `desktop/src-tauri/Cargo.toml` — the actual source; everything else derives
- `tauri.conf.json` — overridden at build time by `--config`, but a checked-in
  value that lies is exactly how issue 2183 happened
- `pyproject.toml` + `__init__.py` — the server's APP_VERSION fallback when no
  BUILD_VERSION is injected

`core` and `android/ffi` stay at 0.1.0 deliberately: internal library crates whose
version reaches no surface, and versioning workspace libs independently of the
app is normal.

Cargo.lock regenerated with `cargo fetch` per ci-requirements — one line, the
version itself. Verified: a tag build now yields 0.2.0 and a dev build 0.2.270,
so stable is an upgrade for every existing install and dev stays ahead of stable.
