Add a blank line before the Trino auth table to satisfy markdownlint (MD058).
The table starts immediately under the heading, which triggers the configured lint warning.

Misleading error when trino-client is installed but missing the expected exports.
The try wraps both the dynamic import("trino-client") and the if (!Trino?.create) throw new Error("Trino.create export not found …") validation. The inner throw is caught by the same catch on line 89 and rewritten to "Trino driver not installed. Run: npm install trino-client". If a user has trino-client installed but its shape changes (e.g., a major-version bump that re-exports differently), they'll be told to run a npm install that won't fix anything.
