Expose rust-hybrid facts protocol shape diagnostics

What to build

Expose a narrow facts-protocol status diagnostic for the rust-hybrid candidate protocol profile output. The profile should make the LowerName, QualifiedName, and FileNodes candidate shapes auditable as protocol-owned candidate-set facts without changing final reference disambiguation semantics or graph output.

Acceptance criteria

• rust-hybrid profile artifacts include candidateProtocol.factsProtocol.shapes.
• LowerName, QualifiedName, and FileNodes each report ownership, status, default route, and semantic boundary.
• Existing candidate lookup behavior and graph semantics are unchanged.
• CLI/profile test coverage verifies the diagnostics contract.
• Roadmap focus advances from 1-3-1 to the next semantic migration slice.

Closing as completed. The current local change exposes candidateProtocol.factsProtocol.shapes for LowerName, QualifiedName, and FileNodes in rust-hybrid profile artifacts, with candidate-set-only semantic boundaries and no resolver behavior change.
