feat(crud): support headless feature registrations

[kauandotnet]

Summary

• add a generic generateControllers: false feature option while retaining service, binding, scope, hook, projection, relation, and registry registration
• exclude headless resources from generated controller and route collision bookkeeping
• retain CrudAdapterError as the cause of mapped Nest HTTP exceptions
• document the headless compatibility-controller pattern and add a Changeset for the next lockstep alpha

Why

Consumers with established wire contracts need to reuse CrudService without also installing generated controllers. Keeping this capability in the upstream module avoids package patches and application-specific forks.

Validation

• pnpm install --frozen-lockfile
• pnpm run check
• pnpm run test
• pnpm run verify:pack
• pnpm run verify:consumer
• pnpm changeset status resolves all five fixed packages to 0.1.0-alpha.5
