Open package URL from detail view

[illutr0n]

In the package detail view, it would be useful to open a URL for the package directly — without leaving the TUI.

For example:

• brew → Homebrew formulae page (e.g. https://formulae.brew.sh/formula/btop) or the package's homepage
• mas → App Store page
• npm/bun → npmjs.com page
• others → whatever URL can be extracted from the package manager metadata

A single keybind (e.g. o) that opens the most relevant URL in the default browser would cover most cases. The formulae/registry page is preferable over the official homepage since it also shows install info, versions, and dependencies.

Environment: macOS 26.3

I like this I'll get it working when I get some time

If this isn’t super urgent, I’d be happy to do this.
I haven't had a proper look at the code yet so I'm not sure if all the URLs are even available?

but regardless I’d be glad to start with the straightforward ones first.
