Migrate Content Resolver from DNF4 (python3-dnf) to DNF5 (python3-libdnf5), restore the package relationship analysis needed for runtime dependency reporting, and fix wildcard package name resolution under DNF5’s stricter query semantics.

Steps

• Reapply "DNF4 to DNF5" (46c6a30) — Core migration across the resolver engine, supporting modules, Docker image, CI workflows, and README.
• Implement DNF5 package relationship analysis (c5960dd) — Rebuilds requires/recommends/supplements reverse-dependency maps using a provides index.
• Handle resolving wildcard package names (b155c4d) — Uses QueryCmp_GLOB for filter_name() and filter_provides() when package names contain wildcard characters.

Key changes

DNF5 migration

• Replace python3-dnf with libdnf5 APIs (Base, Goal, PackageQuery, RepoQuery, DNF5 exception types).
• Add is_package_resolvable() to check packages by name or provides before adding them to a goal.
• Improve transaction error handling and classification (e.g. “nothing provides”, multi-version conflicts).
• Update config_manager.py, historia_data.py, page_generation.py, and utils.py for DNF5 compatibility and cleaner output naming.

Package relationship analysis

• Add _analyze_package_relations() and _resolve_dep_names() to build a provides index and populate reverse dependency maps from requires, recommends, and supplements.
• Restore runtime dependency tracking in view statistics.

Wildcard resolution

• DNF5 defaults to exact matching; wildcard package names now explicitly use QueryCmp_GLOB for name and provides queries.

@yselkowitz , would you mind reviewing these changes when you get a chance?

Based on the results of the staging instance, this seems to fix the issues that forced the early revert.

Is there any other testing we can do to compare the output between the current code and this?

I have a script that I use to do comparisons, but other than that I have been watching it for the last week or more
