Drop support for Node.js 20. The minimum supported version is now `^22.13.0 || ^24.3.0 || >= 26.0.0`.
Node.js 20 reached end-of-life in April 2026 and is no longer actively maintained. This aligns React Native with the upcoming Metro requirement.

This diff updates several Babel packages to their latest versions:
- `babel/code-frame`: 7.29.0
- `babel/generator`: 7.29.1
- `babel/parser`: 7.29.0
- `babel/template`: 7.28.6
- `babel/traverse`: 7.29.0
- `babel/types`: 7.29.0
Not bumping `core` or `runtime` here because they're a bit more involved, and I'm mainly interested in `traverse`. The packages here are the closure of traverse's dependency graph.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/55114
Our official [docs](https://reactnative.dev/docs/set-up-your-environment#node--watchman) require:
> Node 20.19.4 or newer
Currently, our `package.json#engines` fields express this as `"node": ">= 20.19.4"`
This is a bit imprecise because of Node's overlapping release lines - e.g. v24.0.0 is actually older than v20.19.4 (2025-07-15), and the whole v21 line was already EOL before v20.19.4.
The release *date* is relevant because Node.js frequently backports the most important updates - notably, `require(esm)` is already stable in Node 20.19 but is not unflagged in v22 until v22.12.
This makes the `package.json#engines` requirement truer to the documented requirement, dropping some old minors and EOL majors that prevent us using features included in v20.19.
Notably, `require(esm)` is stable and unflagged on all versions supported from this diff.
- v21 and v23 are EOL, so are dropped.
- v22.13 pre-dates 20.19.4 and is the first to have unflagged silent `require(esm)`
- v24.3.0 pre-dates 20.19.4 and is the first to unflag TS-stripping
- Support v25 and newer.

[General][Breaking] Drop support for EOL Node.js lines and old minors.

Summary:
`jscodeshift` is only used in one module (`src/generators/components/GenerateViewConfigJs.js`, but depends on a rather complex dependency chain and has a rather large maintenance burden relative to what it's used for and the value it adds in the codebase.
Since the `GenerateViewConfigJs` module creates simple templates, using `babel/core` (and implicitly `babel/template` and `babel/types`) is a lot simpler and changes little code. The only change this introduces to the output are formatting changes (`singleQuote` and `trailingCommas` options are discarded). The code is otherwise functionally identical.
## Changelog:
[INTERNAL] [CHANGED] - Drop jscodeshift dependency from react-native/codegen
Pull Request resolved: https://github.com/facebook/react-native/pull/49641
Test Plan:
This was tested against a React Native build with the `react-native/babel-plugin-codegen` plugina active and using the snapshots in the repo itself. While the snapshots have changed in formatting, none of the outputs change the code's AST.

Summary:
This pull request replaces the use of mkdirp with Node.js's built-in fs.mkdirSync({ recursive: true }) function, which is available in Node.js version 10.12.0 and above. This change reduces the number of external dependencies and simplifies the codebase by using the native capabilities of Node.js.
The motivation behind this change is to remove the unnecessary mkdirp dependency, as Node.js natively supports recursive directory creation since version 10.12.0. This streamlines the code and reduces the reliance on external libraries.
## Changelog:
[INTERNAL] [REMOVED] - Replaced mkdirp with fs.mkdirSync({ recursive: true }) in build scripts and codegen. Requires Node.js 10.12.0 and above.
Pull Request resolved: https://github.com/facebook/react-native/pull/46388
Test Plan: I ran the build and codegen scripts locally with Node.js version 10.12.0 and above after replacing mkdirp, ensuring the scripts work as expected. No issues were encountered, and all processes, including directory creation and file handling, function correctly.
