Pull request overview

Refactors the skills/ shipped AI-skill documentation to be significantly thinner and more workflow-oriented, relying on the Ignite UI MCP servers for API and documentation facts instead of local reference files.

Changes:

• Consolidates the skills into concise “workflow” hubs (components, grids, theming, generate-from-image) with MCP-first guidance.
• Removes many references/*.md files, pushing detailed setup/feature guidance to MCP docs and tool lookups.
• Updates the skills index/README and AGENTS.md to emphasize MCP-based API discovery and setup snippets.

@ivanvpetrov I think we shouldn't waste time with this PR. The results I'm getting are way worse.
