Release 0.1.1: fix Node publish + bump everything

v0.1.0 reached crates.io, PyPI, and the wickra-wasm npm package, but
the wickra Node binding never published because the workflow called
`napi create-npm-dirs` (plural). The actual napi CLI command is
`create-npm-dir` (singular, per target).

Changes that make the next tag's release actually finish:

- workflow: replace the broken step with a loop that runs
  `napi create-npm-dir -t <triple>` for each of our four build targets.

- workflow: every registry publish step now treats "version already
  uploaded" as success. That makes re-runs (and partial-failure
  recoveries) safe instead of failing the whole job.

- bindings/node/package.json: trim the napi.triples list to the four
  platforms we actually build (linux-x64-gnu, darwin-x64, darwin-arm64,
  win32-x64-msvc). The previous defaults+9-extras configuration would
  have made napi prepublish expect platform packages we never produced.

- bindings/node/index.js: switch from local-only binary lookup to the
  proper napi loader that tries the local `.node` file first and falls
  back to the per-platform npm subpackage that's installed as an
  optional dependency in production.

- Versions across all four published packages bumped to 0.1.1 so the
  Node binding can publish for the first time alongside refreshed
  cargo/pypi/wasm artefacts.
