[Handbook] Add mesheryctl-axi to the repository overview #8189

Current Behavior

The repository overview in the community handbook does not list meshery-extensions/mesheryctl-axi, a new Meshery extension.

Desired Behavior

mesheryctl-axi appears in the repository overview table, alongside the other Meshery command line extensions.

Implementation

This is a small, self-contained change in one file, and a good first issue.

1. Open src/collections/handbook/repository-overview/repo-data.js.

2. Find the "Cloud Native Management Repos" category. Its last entry is "Kubectl Kanvas Snapshot".

3. Add a new entry after it, following the same shape as its neighbors:

   {
     project: "mesheryctl-axi",
     image: meshery,
     language: "TypeScript",
     maintainers_name: ["Yi Nuo", "Shiekh Mohammad"],
     link: ["", ""],
     description:
       "Agent-ergonomic AXI wrapper around mesheryctl with token-efficient TOON output.",
     repository: "https://github.com/meshery-extensions/mesheryctl-axi",
   },

Notes on the fields:

• image: meshery icon
• maintainers_name: taken from the Meshery MAINTAINERS.md, which lists Yi Nuo and Shiekh Mohammad for this repository.
• link: each maintainer's Layer5 community member profile, in the same order as maintainers_name. If a maintainer has no profile page, leave that item as an empty string, as other entries in the file do.

Acceptance Tests

• mesheryctl-axi is listed under "Cloud Native Management Repos" on the repository overview page
• The repository link opens https://github.com/meshery-extensions/mesheryctl-axi
• The site builds and the table renders correctly (make site)
• Commits are signed off
