Cannot set separate url and local_path when assigning to variant.paths

Summary

When assigning paths to variant.paths.repository[arch], variant.paths.debug_repository[arch], or variant.paths.source_repository[arch], there is no way to set different values for url and local_path in the resulting Location object.

Environment

• productmd version: Development branch commit b719ac380fa94a3c68093479957d3ae1aab75c6b
• Python version: 3.14.3

Current Behavior

When assigning to variant paths, the behavior varies depending on the type assigned:

1. Assigning a string: Both url and local_path are set to the same string value

   variant.paths.repository["x86_64"] = "https://example.com/repo"
   # Results in: url="https://example.com/repo", local_path="https://example.com/repo"

2. Assigning a dict: Causes TypeError during serialization

   variant.paths.repository["x86_64"] = {
       "url": "https://example.com/repo",
       "local_path": "compose/repo"
   }
   # Results in: TypeError during ci.dump() - productmd tries to assign the dict to local_path

3. Assigning a Location object: Causes TypeError during serialization

   from productmd.common import Location
   loc = Location()
   loc.url = "https://example.com/repo"
   loc.local_path = "compose/repo"
   variant.paths.repository["x86_64"] = loc
   # Results in: TypeError - productmd wraps it in another Location, setting local_path to the Location object

Expected Behavior

Users should be able to assign a Location object directly without re-wrapping it in another Location

Example of desired usage:

from productmd.composeinfo import ComposeInfo, Variant

ci = ComposeInfo()
# ... set up compose metadata ...

variant = Variant(ci)
variant.id = "BaseOS"
variant.uid = "BaseOS"
variant.name = "BaseOS"
variant.type = "variant"
variant.arches = {"x86_64"}
ci.variants.add(variant)

from productmd.common import Location
loc = Location()
loc.url = "https://pulp.example.com/pulp/content/RHEL-10-10.0-20260311.0/BaseOS-x86_64"
loc.local_path = "BaseOS/x86_64/os"
variant.paths.repository["x86_64"] = loc

ci.dump("composeinfo.json")
