Release 0.1.3: full pipeline working end to end

CI is now green across all 20 jobs:
- Rust on Linux/macOS/Windows
- Python 3.9/3.11/3.12 on Linux/macOS/Windows
- Node 18/20 on Linux/macOS/Windows (Windows previously failed
  because ci.yml built the native module without --platform; fixed
  in the previous commit)
- WASM build
- Cross-library benchmark report

This tag re-publishes 0.1.3 across crates.io / PyPI / npm so a single
version covers every working binding. The release workflow's idempotent
publish steps mean re-runs are safe; the new code in this version is
just the build-script and loader changes that fixed CI.
