Docs: add proposal for Kmesh Headlamp integration architecture

[gouravi19]

Summary

This PR introduces an initial proposal/design document for integrating Kmesh into the Headlamp UI as part of issue #1658.

Included

• Proposed integration goals
• External plugin architecture direction
• Dashboard and observability ideas
• Incremental implementation roadmap
• Future visualization and UX considerations
• Open questions requiring maintainer clarification

Motivation

Initial implementation exploration revealed that Headlamp plugins are expected to live outside the Headlamp core repository. This proposal aims to align future Kmesh integration work with the expected architecture direction before deeper implementation proceeds.

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a formal design proposal for integrating Kmesh observability and management features into the Headlamp UI. The document establishes the architectural direction of using an external plugin to maintain separation from the Headlamp core, while providing a clear, phased roadmap for future development and identifying key open questions for maintainer feedback.

Highlights

• Proposal Introduction: Added a new design document outlining the integration of Kmesh into the Headlamp Kubernetes UI.
• Architecture Strategy: Defined the approach to use an external Headlamp plugin to ensure decoupled releases and maintainability.
• Implementation Roadmap: Proposed a three-phase plan covering foundation, workload observability, and advanced traffic/topology visualization.

Code Review

This pull request introduces a proposal for integrating Kmesh with the Headlamp Kubernetes UI as an external plugin. The proposal outlines a phased implementation roadmap focusing on workload health, traffic observability, and mesh topology visualization while maintaining decoupled release cycles. I have no feedback to provide.

[gouravi19]

This proposal is intended to establish architectural alignment and implementation direction before deeper integration work proceeds. Feedback and maintainer guidance on the expected plugin workflow and repository structure are very welcome.
