Fix #1931. Built-in React hooks such as useEffect() can now be validated by the useExhaustiveDependendies, even when they're not being imported from the React library. To do so, simply configure them like any other user-provided hooks.

Contributed by @arendjr

Implemented #1128. User-provided React hooks can now be configured to track stable results. For example:

"useExhaustiveDependencies": {
    "level": "error",
    "options": {
        "hooks": [{
            "name": "useMyState",
            "stableResult": [
                1
            ]
        }]
    }
}

This will allow the following to be validated:

const [myState, setMyState] = useMyState();
const toggleMyState = useCallback(() => {
  setMyState(!myState);
}, [myState]); // Only `myState` needs to be specified here.

CLI

New features

Add a new command biome migrate prettier. The command will read the file .prettierrc/prettier.json and .prettierignore and map its configuration to Biome's one. Due to the different nature of .prettierignore globs and Biome's globs, it's highly advised to make sure that those still work under Biome.
Now the file name printed in the diagnostics is clickable. If you run the CLI from your editor, you can <kbd> Ctrl</kbd>/<kbd title="Cmd">⌘</kbd> + Click on the file name, and the editor will open said file. If row and columns are specified e.g. file.js:32:7, the editor will set the cursor right in that position. Contributed by @ematipico

The CLI now consistently shows the number of errors and warnings emitted. Contributed by @ematipico

Bug fixes

Don't process files under an ignored directory.

Previously, Biome processed all files in the traversed hierarchy, even the files under an ignored directory. Now, it completely skips the content of ignored directories.

For now, directories cannot be ignored using files.include in the configuration file. This is a known limitation that we want to address in a future release.

For instance, if you have a project with a folder src and a folder test, the following configuration doesn't completely ignore test.
```
{
  "files": {
    "include": ["src"]
  }
}
```
Biome will traverse test, however all files of the directory are correctly ignored. This can result in file system errors, if Biome encounters dangling symbolic links or files with higher permissions.

To avoid traversing the test directory, you should ignore the directory using ignore:
```
{
  "files": {
    "include": ["src"],
    "ignore": ["test"]
  }
}
```

Contributed by @ematipico

The command format now emits parsing diagnostics if there are any, and it will terminate with a non-zero exit code. Contributed by @ematipico

Configuration

New features

Add the ability to resolve the configuration files defined inside extends from the node_modules/ directory.

If you want to resolve a configuration file that matches the specifier @org/configs/biome, then your package.json file must look this:
```
{
  "name": "@org/configs",
  "exports": {
    "./biome": "./biome.json"
  }
}
```
And the biome.json file that "imports" said configuration, will look like this:
```
{
  "extends": "@org/configs/biome"
}
```
Read the documentation to better understand how it works, expectations and restrictions.

Enhancements

composer.json, deno.json, jsconfig.json, package.json and tsconfig.json are no longer protected files.

This means that you can now format them.

If you want to ignore these files, you can use the files.ignore configuration:
```
{
  "files": {
    "ignore": [
      "composer.json",
      "jsconfig.json",
      "package.json",

useNamingConvention now supports unicase letters (#1786).

```
const 안녕하세요 = { 안녕하세요: 0 };

Bug fixes

The fix of useArrowFunction now adds parentheses around the arrow function in more cases where it is needed (#1524).

A function expression doesn't need parentheses in most expressions where it can appear. This is not the case with the arrow function. We previously added parentheses when the function appears in a call or member expression. We now add parentheses in binary-like expressions and other cases where they are needed, hopefully covering all cases.

Previously:
```
