v1.3.1 - Release

### Security

- **Bumped `immutable` 5.1.6 -> 5.1.9** to clear two high-severity
  denial-of-service advisories (GHSA-v56q-mh7h-f735, GHSA-xvcm-6775-5m9r).
  `immutable` is a transitive **dev** dependency pulled in by `sass` and only
  runs during the build, never in the shipped app - so the advisories were not
  exploitable against users - but this clears the alerts.

### Changed

- **Relicensed from PolyForm Noncommercial 1.0.0 to MIT + Commons Clause.**
  PolyForm NC barred all commercial use, including a company running NetGraph on
  its own internal network. The new terms allow use (companies included),
  modification, and free redistribution, and forbid only selling the software
  (per the Commons Clause). Updated `LICENSE`, `package.json`, the README badge
  and license note, and CONTRIBUTING.
- **Updated dependencies** - `lucide-static` 1.24.0 -> 1.26.0 (Lucide icon set),
  plus build and CI tooling (`happy-dom`, `sass`, `actions/checkout`).
