Add a platform plugin for claude desktop

[AlanSherman]

Summary

Adds a new lfx-platform Claude Desktop plugin that packages platform engineering tools, skills, and MCP server configuration for the LFX v2 Kubernetes platform.

What's Changed

Plugin scaffold (lfx-platform/)

• .claude-plugin/plugin.json — Plugin manifest declaring the lfx-platform plugin (v0.1.0), authored by the Linux Foundation, with a description of its tooling scope (Datadog, Kubernetes, AWS, GitHub, ArgoCD).
• .mcp.json — MCP server configuration wiring in the Datadog and GitHub connectors, plus extension references for the three Kubernetes clusters (dev, stag, prod) and three AWS environments (lfx-dev, lfx-stag, lfx-prod). The K8s and AWS servers are distributed as Desktop Extensions (.mcpb) and installed separately.

Commands

• commands/platform-setup.md — Guided setup command to walk users through installing the required Desktop Extensions.
• commands/platform-deploy.md — Deployment workflow command.

Skill: platform-troubleshoot

• SKILL.md — Troubleshooting skill definition for the LFX platform.
• Reference docs covering: ArgoCD structure, AWS, Datadog, environment mapping, IaC repos, and Kubernetes — giving Claude the context it needs to assist with platform-level debugging.

Why

This packages the LFX platform engineering context and tooling into a distributable Claude Desktop plugin, so engineers can get Claude assistance for platform troubleshooting and deployments with all the right MCP servers and reference knowledge pre-configured.

Notes

• This is currently a draft PR — likely still in progress.
• The K8s and AWS MCP servers require manual extension installation (.mcpb files); platform-setup guides users through this.
