 * - Sets `title` from the first `# h1` heading if one is present — otherwise leaves it undefined
 *   (a confident title only).
 * - When a `title` is found, strips the leading `# h1` from `content` so renderers (which show
 *   `title` separately) don't display the heading twice.
 * - Sets `description` to the first prose paragraph as a plain-text summary (used for card listings and `<meta>`).

/**
 * Parse a markdown source string once and derive its `title` and `description` in a single pass.
 * - `title` — plain text of the first `# h1` heading, or `undefined` if there is none.
 * - `description` — plain-text summary of the first prose paragraph, or `undefined` if there is none.
 * - Both query the parsed markup tree, so inline syntax (`` `code` ``, `*emphasis*`, links) resolves to clean plain text.
 *
 * @param text The markdown source string (a markdown file's text, or a JSDoc description).
 * @returns An object whose `title` and `description` are each a plain string, or `undefined` when absent.
