Allow cross-registry refinements

[lmolkova]

When refining something from dependency, weaver fails with

  × The following `extends` clause reference is not resolved for the group
  │ 'refined.request'.
  │ `extends` clause reference: span.server.request
  │ Provenance: Some(Provenance { schema_url: SchemaUrl { url: "https://span-
  │ consumer.example.com/schemas/1.0.0", name_range: 8..41, version_range:
  │ 42..47 }, path: "data/registry-test-v2-dep/span_registry/registry/
  │ registry.yaml" })

fixing it

Pull request overview

This PR fixes cross-registry (dependency) refinement/extends resolution by preserving the extended group’s signal type during resolution, enabling v1→v2 conversion and inheritance to work when the parent group is not present in the local registry.

Changes:

• Record the parent group’s GroupType in GroupLineage during extends resolution.
• Improve v2 dependency group lookup to handle both prefixed (v1-style) and unprefixed (v2-style) IDs and to preserve per-attribute requirement levels/sampling relevance.
• Add end-to-end resolver fixtures/tests covering metric/span/event (and an ignored entity) refinements over a published v2 dependency.

Nice cleanup / extension!

I find it amusing this is the key fix here :)
