LayerZ Schema Validation

lz-schema v0.35.1 provides TypeScript type definitions and Zod validation schemas for the LayerZ API entities. It is part of the LayerZ project and is co-released with the API. Key differentiator: tightly coupled with LayerZ API contracts, ensuring schema consistency. Schemas include campaign, workspace, and other domain models. Release cadence follows LayerZ backend updates. Requires Zod as a peer dependency.
