fix(rvf-wasm): fix Node.js CJS/ESM glue and add rvf-node CI

- Fix WASM glue: detect Node.js properly instead of relying on fetch()
  (fetch on file:// URLs fails in Node.js 18-21)
- Support both CJS require() and ESM import via exports map
- Add .mjs ESM wrapper for dual-format support
- Remove "type": "module" for CJS compatibility
- Bump rvf-wasm to 0.1.5
- Add build-rvf-node.yml CI workflow for cross-platform NAPI builds
  (linux-x64-gnu, linux-arm64-gnu, darwin-x64, darwin-arm64, win32-x64-msvc)
- Fix wasm-dedup-check CI: use --ignore-scripts --omit=optional to avoid
  EBADPLATFORM errors from platform-specific workspace packages
