Subject: [PATCH 3/7] feat(validation): flat src/schema modules and loader for
 sdk-generator output

Replace src/validation/<resource>/<action>.validation.ts with flat
src/schema/<resource_snake>.schema.ts (and shared.schema.ts), matching the
sdk-generator VALIDATOR_ZOD layout. Each file aggregates all body/query
schemas for that resource and exports z.infer-derived types per action.

- Point validationLoader at ./schema/<resource_snake>.schema.js (CJS build).
- Resolve exports using PascalCase body const names aligned with
  ZodNamingStrategy.bodySchemaName in sdk-generator.

Regenerated from the same OpenAPI spec via sdk-generator; requires the paired
validator emitter changes in sdk-generator.

Subject: [PATCH 4/7] refactor(validation): use native import() for schema
 loading, defer to API call time

Replace manual createRequire-based module resolution with native dynamic import(),
allowing TypeScript compiler to handle ESM/CJS transpilation automatically. Schema
loading is now deferred to API call time (lazy), preserving synchronous SDK
initialization while maintaining validation functionality in both module systems.

cache redundant. This simplifies the code while maintaining the same
performance characteristics.
