ci: fix maturin and wasm-pack jobs

Two unrelated failures in the post-release CI run:

- Python jobs: `maturin develop` requires an activated virtualenv on
  CI runners that don't have a system Python set up that way. Switch
  to `maturin build --release --out dist` followed by `pip install
  --find-links dist`, which is venv-agnostic and OS-portable.

- WASM job: the wasm-opt bundled with wasm-pack is older than the WASM
  features rustc 1.92 enables by default. The fix is to opt every feature
  in explicitly via the package metadata — reference-types, multivalue,
  bulk-memory, sign-ext, mutable-globals, nontrapping-float-to-int — so
  wasm-opt accepts the input.

Same code as before; only the build steps and the wasm-opt config changed.
