v1.5.1

Patch release on top of v1.5.0 (the newsletter system release).

Fixed

• CI/build: ignore the laravel/framework 11.x security advisories that Composer 2.9+ excludes during dependency resolution, which was breaking the Laravel 11 compatibility test matrix. Scoped to this package's root config.audit.ignore — does not propagate to host apps. No runtime/code changes.

See v1.5.0 for the newsletter system, add_follower, ticket subjects, and permission enforcement.
