Description

The marketplace name field in .claude-plugin/marketplace.json is set to "Context Engine by Augmentcode", which contains spaces.

Claude Code's /plugin command validates marketplace names and requires kebab-case:

Invalid schema: .claude-plugin/marketplace.json name: Marketplace name cannot contain spaces. 
Use kebab-case (e.g., "my-marketplace")

Steps to Reproduce

1. Open Claude Code
2. Run /plugin
3. Select "Add Marketplace"
4. Enter augmentcode/context-engine-plugin
5. Observe the validation error

Expected Behavior

The marketplace should install successfully.

Suggested Fix

Change the name field from "Context Engine by Augmentcode" to "context-engine-by-augmentcode" (or similar kebab-case name).
