/**
 * Pick which lines to render for a SQL editor error.
 *
 * pg-meta returns `formattedError` with multi-line ERROR/HINT/LINE output from Postgres.
 * Historically only `message` was reliably populated end-to-end, which is why the UI also
 * falls back to splitting `message` on newlines — e.g. the enhanced permission-denied HINT
 * added by briven/postgres#2084 arrives in the message body on some paths.
 *
 * Returns an empty array when the error is single-line (message only) — callers fall back to
 * a plain "Error: {message}" rendering in that case.
