/**
 * PERSONA commitment definition
 *
 * The PERSONA commitment modifies the agent's personality and character in the system message.
 * It defines who the agent is, their background, expertise, and personality traits.
 *
 * Key features:
 * - Multiple PERSONA commitments are automatically merged into one
 * - Content is placed at the beginning of the system message
 * - Original content with comments is preserved in metadata.PERSONA
 * - Comments (# PERSONA) are removed from the final system message
 *
 * Example usage in agent source:
 *
 * ```book
 * PERSONA You are a helpful programming assistant with expertise in TypeScript and React
 * PERSONA You have deep knowledge of modern web development practices
 * ```
 *
 * The above will be merged into a single persona section at the beginning of the system message.
 *
 * @private [🪔] Maybe export the commitments through some package
