Code Review

This pull request implements the resolution of virtual RPM provides to actual package names using 'rpm -q --whatprovides' during artifact preparation and installation verification. In 'verify_installation.py', replace the dictionary comprehension for 'verify_map' with a loop using 'setdefault' and 'tmt.utils.uniq' to prevent overwriting entries when multiple virtual provides resolve to the same package name.

[gemini-code-assist]

The dictionary comprehension used to construct verify_map will overwrite entries if multiple virtual provides resolve to the same package name (e.g., /usr/bin/sh and sh both resolving to bash). This results in the loss of repository verification data for the overwritten entries. Use a loop with setdefault to merge the repository lists instead.

	verify_map: dict[str, list[str]] = {
	resolved.get(pkg, pkg): repos for pkg, repos in self.data.verify.items()
	}
	verify_map: dict[str, list[str]] = {}
	for pkg, repos in self.data.verify.items():
	verify_map.setdefault(resolved.get(pkg, pkg), []).extend(repos)
	verify_map = {name: tmt.utils.uniq(repos) for name, repos in verify_map.items()}
