feat: fully type CRUD field vocabularies

[kauandotnet]

Summary

• require each CRUD resource to declare one authoritative, non-empty field vocabulary
• propagate exact logical field unions through IDs, paths, query options, relations, scopes, cursors, predicates, ordering, mappings, and every adapter binding
• derive persistence field unions for memory, TypeORM, Drizzle, and Prisma, including typed upsert conflict and overwrite tuples
• add compile-negative coverage, runtime validation, documentation, consumer migrations, and a changeset

Breaking changes

• defineCrudResource now requires fields
• binding-level fields options were removed from defineCrudBinding and all concrete bind helpers
• authored field names outside the resource or persistence vocabulary now fail compilation

Verification

• pnpm run verify
• 328 unit tests passed
• 65 PostgreSQL integration tests passed
• all five packed-package consumer checks passed
