release: bump 0.8.1 -> 0.8.2 (#245)

Patch release shipping the R WebAssembly build fix (#244): `bindings/r/configure` builds the C ABI from source for `wasm32-unknown-emscripten`, so r-universe's webR build stops failing. Also carries the shared Go badge in `bindings/go/README.md`. Version bumped across all manual touchpoints via `bump_version.py` (incl. DESCRIPTION + csproj, which had drifted before).
