fix

When running `bun update` on packages that don't exist in package.json,
the output now shows "added" instead of "installed" to clearly distinguish
between packages that were:
- Updated from an existing version (shows "updated")
- Newly added because they didn't exist before (shows "added")

This prevents confusion when users mistype package names during updates,
as they'll now see "added package-name" instead of the generic "installed"
message that was identical to the update output.

Fixes the issue where `bun update zod-openapi` would install `openapi-zod`
and show "installed" without clearly indicating it was a new package.
