Add Responsible Security Disclosure comment to main plugin file

[thomasplevy]

Summary

Add a Responsible Security Disclosure comment block to the plugin’s main PHP entry file, immediately below the standard WordPress plugin header comment (Plugin Name:, Plugin URI:, Description:, etc.).

This supports the organization-wide security disclosure contact tracked in the parent issue.

Comment block to add

Place the following block directly after the closing */ of the plugin header comment, before other code:

/**
 * * * * * * * * * * * * * * * * * * * * * * *
 *                                           *
 * Reporting a Security Vulnerability        *
 *                                           *
 * Please disclose any security issues or    *
 * vulnerabilities to security@caseproof.com *
 *                                           *
 * * * * * * * * * * * * * * * * * * * * * * *
 */

Email: Use security@caseproof.com as above, or a product-specific alias such as security@{productdomain}.com (e.g. security@memberpress.com) if preferred for this product.
