Inject Up-to-date Library Docs Into Llm Prompts

Context7 is an MCP server and CLI that pulls version-specific, up-to-date library documentation and code examples directly into LLM prompts. It exposes resolve-library-id and query-docs tools (or ctx7 library/docs commands) so coding agents stop hallucinating outdated APIs.
