Feature request: ntfy tags and title from URL query parameters

[cmerkle]

Dockhand uses Apprise-style ntfy URLs but URL query parameters like ?tags= and ?title= are ignored. Looking at the source, the ntfy handler builds its own headers and hardcodes tags to just the event type:

const i = {
  Title: e.title,
  Priority: e.type === "error" ? "5" : e.type === "warning" ? "4" : "3",
  Tags: e.type || "info"
};

This means there is no way to set custom tags or a title on ntfy notifications — the URL query params are never parsed.

Would be great if the ntfy handler parsed query parameters from the URL and used them to override or supplement the default headers, similar to how Apprise handles ?tags= and ?priority=. That way users could set something like:

ntfys://user:pass@ntfy.example.com/topic?tags=ship,whale&title=Dockhand

and have those values show up in the notification.
