Support hooks

## Proposal

Add hooks for run process for each files, example:

```json
{
"hooks": {
"afterOneFileWrite": ["prettier --write"]
}
}
```

### Hooks

* beforeAllFileWrite
* beforeOneFileWrite
* afterOneFileWrite
* afterAllFileWrite

The proposal defines four hook points—beforeAllFileWrite, beforeOneFileWrite, afterOneFileWrite, and afterAllFileWrite—and shows a hooks configuration with a command. Start by locating the file-writing pipeline and configuration entry point, then determine how each command should be run and what completion means for every lifecycle stage.
