Latest MUI 9 migration codemod broken

[nidolam]

Steps to reproduce

Steps:

1. Excute the command npx @mui/codemod@latest deprecations/accordion-props "src/**/*.jsx"
2. You get the error Error: Transform 'deprecations/accordion-props' not found
3. The same happens with the other codemods

Current behavior

Hi folks,
if I execute the following command:

npx @mui/codemod@latest deprecations/accordion-props "src/**/*.jsx"

then I get the following error

/Users/xyz/.npm/_npx/2aacf93ee2439f59/node_modules/@mui/codemod/codemod.js:34
      throw new Error(`Transform '${transform}' not found. Check out ${path.resolve(__dirname, './README.md for a list of available codemods.')}`);
            ^

Error: Transform 'deprecations/accordion-props' not found. Check out /Users/xyz/.npm/_npx/2aacf93ee2439f59/node_modules/@mui/codemod/README.md for a list of available codemods.

Node.js v24.19.0

It works with version 9.1.0:

npx @mui/codemod@9.1.0 deprecations/accordion-props "src/**/*.jsx"

Expected behavior

It should work the same way it worked with version 9.1.0

Confidence: high — the published archives and package behavior differ across the reported versions
Reproduction: verified — the 9.3.0 archive omits the transforms present in 9.1.0, and packing with the current release tooling reproduces the omission
Duplicates: none found
Affected component: @mui/codemod CLI transform resolution

Next actions:

1. Update the codemod package's publishing configuration so every built transform is included in the published archive.
2. Add a package-archive test that asserts representative transforms, including deprecations/accordion-props, are present before publishing.
3. Publish a patch release and verify the transform with the documented npx @mui/codemod@latest command.
