[BUG] Error occurs with Chocolatey local repository

Start with the Chocolatey local file-source reproduction described in the issue and inspect the BaseNuGet.FindPackages_UnSafe stack-trace entry. Run a search against a local file:// source and compare it with the Chocolatey community source. Done means UniGetUI finds packages from the local source without reporting that the file scheme is unsupported.

Please confirm these before moving forward

• I have searched for my issue and have not found a work-in-progress/duplicate/resolved issue.
• I have tested that this issue has not been fixed in the latest (beta or stable) release.
• I have checked the FAQ section for solutions.

UniGetUI Version

2026.3.0

Windows version, edition, and architecture

Windows 11 Pro, 26200.9457, x64

Describe your issue

I've added a new local source to Chocolatey. The source is properly detected by UniGetUI when I check into Chocolatey options.
However, when I look for a package, nothing is found, whereas if I use Chocolatey CLI (choco find or choco install) I have no issue to find and install my package.
Moreover, after I installed the package using Chocolatey CLI, the package is properly listed in "installed packages" with source as "Chocolatey: community".

Steps to reproduce the issue

1. Add a new file based source to Chocolatey (ie file://... url) with any valid nupkg file in this folder.
2. Perform any search with UniGetUI
3. Look for logs
