Document UserNotifications migration examples

[Jesssullivan]

Goal

Make the Apple migration story concrete without claiming full UNUserNotificationCenter parity.

Context

The current macOS backend uses osascript display notification. It covers simple title/body local notification delivery, but not categories, actions, scheduling, attachments, APNs, delivered-notification queries, sounds, or delegate callbacks.

Docs: https://transscendsurvival.org/zig-notify/guides/apple-interop/

Scope

• Add a small migration table from UNMutableNotificationContent title/body concepts to zig_notify_send.
• Clearly mark non-goals and unavailable surfaces.
• Include one Swift or Objective-C snippet that calls the C ABI for title/body send.
• Do not add a direct UNUserNotificationCenter backend in this issue.

Validation

• python3 scripts/gen_docs.py
• mkdocs build --strict

I see you're looking to document a migration from UNMutableNotificationContent to zig_notify_send, avoiding full UNUserNotificationCenter parity. I'd handle this by creating a concise migration table and adding a Swift snippet for the C ABI call. Can have a PR up in 3 days. I've built similar notification integration guides for macOS projects before.

How kind! That'd be awesome. 🙏
