/**
 * META LINK commitment definition
 *
 * The `META LINK` commitment represents the link to the person from whom the agent is created.
 * This commitment is special because it doesn't affect the system message,
 * but is handled separately in the parsing logic for profile display.
 *
 * Example usage in agent source:
 *
 * ```
 * META LINK https://twitter.com/username
 * META LINK https://linkedin.com/in/profile
 * META LINK https://github.com/username
 * ```
 *
 * Multiple `META LINK` commitments can be used when there are multiple sources:
 *
 * ```book
 * META LINK https://twitter.com/username
 * META LINK https://linkedin.com/in/profile
 * ```
 *
 * @private [🪔] Maybe export the commitments through some package
