chore(deps-dev): bump @nestjs/schematics from 11.1.0 to 12.0.0

[dependabot]

Bumps @nestjs/schematics from 11.1.0 to 12.0.0.

Release notes

Sourced from @​nestjs/schematics's releases.

Release 12.0.0

What's Changed

@nestjs/schematics is now a native ES module, and the major version is aligned with the Nest 12 release line. Beyond the package itself going ESM, the bigger change is what it generates: nest new now scaffolds ESM applications by default, and a brand-new nest upgrade schematic migrates existing v11 projects to v12.

ESM migration

The package is published as pure ESM ("type": "module", compiled with NodeNext). All internal imports carry explicit .js extensions and the build output is ESM-only.

The package now requires Node.js >= 22.12.0 and declares a typescript >= 6.0.0 peer dependency. prettier ^3 remains an optional peer, used only when --format is passed.

require(esm) — CommonJS still works

You do not need to convert your tooling to ESM. Thanks to Node's require(esm) support, CommonJS consumers can still require('@nestjs/schematics') on the supported Node versions, so custom collections and CJS scripts that drive the schematics programmatically keep working unchanged.

nest new generates ESM by default

The application schematic gained a type option (esm | cjs) that defaults to esm:

Which module system would you like to use?
> ESM (ES Modules)         [ with vitest ]
  CJS (CommonJS)           [ with jest ]

• ESM projects get "type": "module", Vitest as the test runner (vitest.config.ts / vitest.config.e2e.ts), and "types": ["vitest/globals", "node"].
• CJS projects keep Jest, but the Jest configuration has moved out of package.json into a dedicated jest.config.ts.

Pass --type cjs (or answer the prompt) to keep the classic CommonJS layout.

Generated project defaults

• TypeScript 6, with module/moduleResolution set to nodenext, resolvePackageJsonExports: true, isolatedModules: true, and target: ES2023.
• oxlint replaces ESLint. New projects ship an oxlint.json and a "lint": "oxlint src/ test/" script instead of the ESLint config and its plugin chain.
• Rspack replaces webpack as the default builder in nest-cli.json.
• Nest dependencies are pinned to the v12 line (@nestjs/common, @nestjs/core, @nestjs/platform-express, @nestjs/testing).

ESM-aware generators

Every element generator (module, controller, service, resource, middleware, pipe, …) now detects whether the target project is ESM and appends .js to generated relative imports accordingly — including the imports it injects into an existing @Module() when wiring up a newly generated element. CJS projects are unaffected.

New: nest upgrade

A new schematic (aliased nest update) migrates a Nest v11 project to v12. It refuses to run on anything that isn't v11, then applies the migration in steps and prints a report of every change, every follow-up action, and every warning.

Dependencies — bumps all known @nestjs/* packages to ^12.0.0 (GraphQL packages to ^14.0.0), raises typescript to ^6.0.0 and engines.node to >=20.19.0, and reports any @nestjs/* package whose v12-compatible release it doesn't know about.

tsconfig — flags module: commonjs with legacy module resolution and any moduleResolution that TypeScript 6 dropped, and points out a missing rootDir in tsconfig.build.json (TS6 error TS5011).

@nestjs/config — moves library-specific validationOptions (Joi's allowUnknown, abortEarly, …) under validationOptions.libraryOptions, and raises joi to ^18 for its Standard Schema support.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
