story: evaluate OpenAPI export for records and value objects

[soulcodingmatt]

Story

As a project maintainer, I want to evaluate whether OpenAPI schema export makes sense for Records and Value Objects (as defined in Equilibrium), so that I can make an informed decision about extending the export feature beyond DTOs.

Context

Parent epic: #18

DTOs are the primary use case for OpenAPI export. Records and Value Objects have different semantics — Records are immutable data carriers, VOs represent domain concepts with equality by value. Whether exporting these to OpenAPI schemas is useful depends on how they're used in API boundaries.

Acceptance Criteria

• A technical evaluation document is produced covering: use cases for Record/VO export, semantic differences from DTO export, and implementation complexity
• The document includes a recommendation (export both, export Records only, or DTOs only)
• If export is recommended, the approach is documented (reuse DTO export logic vs separate generator)

Acceptance Criteria
