feat: add install_devcycle_sdk MCP tool and build-time prompt fetcher

[jonathannorris]

Summary

Adds a new MCP tool to fetch DevCycle install prompts by guide name and vendors the list of available guides at build time.

Changes

• Add install_devcycle_sdk MCP tool that returns the raw Markdown for a guide.
• Build-time script scripts/fetch-install-prompts.js to:
  • Fetch all install-prompts/**/*.md (including OpenFeature)
  • Generate src/mcp/tools/installGuides.generated.ts (enum of valid slugs)
  • Log generation; on fetch failure, proceed with previously generated file if present
• Update package.json to run the generator in yarn build.
• Register the tool and allow plain string returns in MCP server.
• Mark generated file as linguist-generated in .gitattributes.

Usage

• Call install_devcycle_sdk with guide set to any slug from the generated list (e.g., react, openfeature/react, android-openfeature), and the tool returns the Markdown content.

References

• Install prompts source: AI-Prompts-And-Rules/install-prompts
