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).

+## [0.8.2] - 2026-06-10
+### Fixed
+- **R binding builds for WebAssembly** — `bindings/r/configure` now builds the
+  C ABI from source for the `wasm32-unknown-emscripten` target (r-universe /
+  webR) using the build image's cargo + emscripten, instead of failing with
+  "unsupported OS Emscripten". rayon is dropped on wasm via
+  `--no-default-features`; the indicators are pure computation, so the serial
+  path is functionally identical.
+
+## [0.8.1] - 2026-06-10
+### Fixed
+- **`wickra-go` license** — the release-time Go module mirror now ships the dual
+  `LICENSE-MIT` and `LICENSE-APACHE` files, so pkg.go.dev detects a
+  redistributable license for `github.com/wickra-lib/wickra-go`. The previous
+  mirror shipped no license file.
