DOC-3471, DOC-3476: Output Markdown endpoints from LLM file generator and add Context7 MCP instructions

Add toMarkdownEndpoints() to generate-llm-files.js so generated
llms.txt and llms-full.txt URLs point to index.md Markdown endpoints
instead of trailing-slash HTML pages.

Add Context7 MCP setup section to llms.txt with Cursor and Claude
Code configuration instructions for live documentation lookups.
