feat: add hot-hook/register entrypoint loader

[Julien-R44]

This PR adds a new way of configuring hot-hook. This allows you to configure hot-hook without having to modify your codebase.

We introduce a new hot-hook/register entrypoint that can be used with Node.JS's --import flag. By using this method, the Hot Hook hook will be loaded at application startup without you needing to use hot.init in your codebase. It can be used as follows:

node --import=hot-hook/register ./src/index.js

Be careful if you also use a loader to transpile to TS (ts-node or tsx), hot-hook must be placed in the second position, after the TS loader :

node --import=tsx --import=hot-hook/register ./src/index.ts

To configure boundaries and other files, you'll need to use your application's package.json file, in the hot-hook key. For example:

// package.json
{
  "hotHook": {
    "boundaries": [
      "./src/controllers/**/*.tsx"
    ]
  }
}
