Migrate to UNUserNotificationCenter

[vjeantet]

Big changes ahead !

I am migrating alerter from the legacy notification framework to UNUserNotificationCenter.

Why? Apple has deprecated the old NSUserNotification API, and starting with macOS Sequoia, some private APIs are already being actively blocked.
It's time to move forward.

What this means:

• Better compatibility with macOS Sequoia and future releases
• Access to richer notification features
• Long-term maintainability

Call for testers 🙏

Once the migration branch is ready, I will need help validating that everything works as expected across different macOS versions. If you are willing to test the next release and report any regressions, please drop a comment here. every bit of feedback counts !

Stay tuned.

I'm hope to have availability to help test. I'm on Sequoia, and this is mostly my subscribing to the issue. Depending on when you're ready I may have time to do some quick tests.

I assume you've already started the migration? If you haven't and this is on your future roadmap let me know if you want an attempt from someone else.

I am using this nice project extensively and am up for testing v2 on Tahoe!
