feat(db-postgres,db-sqlite,db-vercel-postgres,db-d1-sqlite,drizzle)!: remove /types subpath exports

[paulpopus]

Summary

• Removes the deprecated /types subpath export from @payloadcms/drizzle, @payloadcms/db-postgres, @payloadcms/db-sqlite, @payloadcms/db-vercel-postgres, and @payloadcms/db-d1-sqlite. All types are available from the main package entry point.
• Migrates all internal imports (DrizzleAdapter, BuildQueryJoinAliases, PostgresAdapter, SQLiteAdapter) from the /types subpath to the main package.
• Adds the migrate-db-types-subpath codemod transform to @payloadcms/codemod to auto-migrate user projects.
• Documents the breaking change in the 3.0→4.0 migration guide.

Breaking Changes

@payloadcms/drizzle/types → @payloadcms/drizzle

- import type { DrizzleAdapter, BuildQueryJoinAliases } from '@payloadcms/drizzle/types'
+ import type { DrizzleAdapter, BuildQueryJoinAliases } from '@payloadcms/drizzle'

@payloadcms/db-postgres/types → @payloadcms/db-postgres

- import type { PostgresAdapter, GeneratedDatabaseSchema } from '@payloadcms/db-postgres/types'
+ import type { PostgresAdapter, GeneratedDatabaseSchema } from '@payloadcms/db-postgres'

@payloadcms/db-sqlite/types → @payloadcms/db-sqlite

- import type { SQLiteAdapter, SQLiteSchemaHook } from '@payloadcms/db-sqlite/types'
+ import type { SQLiteAdapter, SQLiteSchemaHook } from '@payloadcms/db-sqlite'

@payloadcms/db-vercel-postgres/types → @payloadcms/db-vercel-postgres

- import type { VercelPostgresAdapter } from '@payloadcms/db-vercel-postgres/types'
+ import type { VercelPostgresAdapter } from '@payloadcms/db-vercel-postgres'

@payloadcms/db-d1-sqlite/types → @payloadcms/db-d1-sqlite

- import type { SQLiteD1Adapter } from '@payloadcms/db-d1-sqlite/types'
+ import type { SQLiteD1Adapter } from '@payloadcms/db-d1-sqlite'

declare module augmentations

Generated schema files that augment GeneratedDatabaseSchema must also update the module path:

- declare module '@payloadcms/db-postgres/types' {
+ declare module '@payloadcms/db-postgres' {
    export interface GeneratedDatabaseSchema {
      schema: DatabaseSchema
    }
  }

Migration

Run the codemod to migrate automatically:

npx @payloadcms/codemod --transform migrate-db-types-subpath

The codemod handles import declarations, re-export declarations, and declare module augmentations. It is idempotent and safe to run on partially-migrated projects.
