/**
 * Tool registry for the diagram chatbot.
 *
 * Each entry in CHAT_TOOLS maps a tool name to:
 *  - description / inputSchema  -- forwarded to the LLM as tool definitions
 *  - execute()                  -- calls the matching handler and returns
 *                                 { result, filePaths } where filePaths is
 *                                 the list of source files to highlight in
 *                                 the dependency graph.
 *
 * To add a future MCP tool: add one entry here pointing to any handler.
