Broken GitHub source links for monorepo packages when repository.url includes .git

[cochinescu]

Describe the bug

npmx is generating a broken GitHub source link for @agentmarkup/vite.

On the package page, the source link goes to:

https://github.com/agentmarkup/agentmarkup.git/tree/HEAD/packages/vite

That URL returns 404.

The correct GitHub URL is:

https://github.com/agentmarkup/agentmarkup/tree/HEAD/packages/vite

It looks like npmx is using npm registry repository.url + repository.directory, but not normalizing the repo URL before building the GitHub web link.

Additional context

Repro:

• https://npmx.dev/package/@agentmarkup/vite

The same problem appears to affect:

• @agentmarkup/core
• @agentmarkup/astro

Important detail:

• the repo manifest is already https://github.com/agentmarkup/agentmarkup
• the published npm tarballs also contain the clean URL
• npm registry metadata exposes git+https://github.com/agentmarkup/agentmarkup.git

So the bug seems to be in link construction from registry metadata, not in the package itself.
