Pull Request

🤨 Rationale

There is a requirement to use a chip‑like UI element in the SLE, which is an Angular application. Therefore, add an Angular wrapper for the nimble-chip component as part of #413.

See the nimble-chip component spec for details.

👩‍💻 Implementation

• Add and export a new Angular directive and module for the nimble-chip component
• Update the component status table to "ready" for Angular support

🧪 Testing

• Added unit tests for the directive.
• Manually tested in the example Angular app
  

✅ Checklist

• I have updated the project documentation to reflect my changes or determined no changes are needed.
