+ * Publora MCP server — stdio entry point.
+ *
+ * Runs the same tools as the HTTP server (src/index.js), but over the stdio
+ * transport so the server can be launched locally by MCP clients (Claude
+ * Desktop, Cursor, etc.) and by tooling that wraps stdio servers.
+ *
+ * The HTTP server in src/index.js is untouched; this file only reuses its
+ * createApiClient + registerTools and connects a StdioServerTransport.
+ *
+ * API key is read from the PUBLORA_API_KEY env var. Listing tools
+ * (introspection) works without a key; a key is only needed to call tools.
