Core: Split Storybook CLI

[kasperpeulen]

What I did

Implements the CLI split RFC:
#23590

The build and dev command is moved to @storybook/core/cli together with other shared CLI logic.
The init command is moved to create-storybook
All other commands are moved @storybook/cli.

In the storybook package there is a proxy.ts file that orchestrates the storybook package to forward the command with npx to the right package:

storybook/code/lib/cli/src/proxy.ts

Lines 1 to 21 in d085503

	import { spawn } from 'child_process';
	import { versions } from '@storybook/core/common';
	const args = process.argv.slice(2);
	if (['dev', 'build'].includes(args[0])) {
	require('@storybook/core/cli/bin');
	} else {
	const proxiedArgs =
	args[0] === 'init'
	? [`create-storybook@${versions.storybook}`, ...args.slice(1)]
	: [`@storybook/cli@${versions.storybook}`, ...args];
	const command = ['npx', '--yes', ...proxiedArgs];
	const child = spawn(command[0], command.slice(1), { stdio: 'inherit' });
	child.on('exit', (code) => {
	if (code != null) {
	process.exit(code);
	}
	process.exit(1);
	});
	}

By using npx, the user doesn't have to install a bunch of dependencies, such as jscodeshift, that are not needed for basic storybook commands. It now only needs to download that when it actually needs it.

This makes sure that the storybook package is as lean as possible. We remove 370 packages and 70MB install size with this PR.

Next to that, we can now consolidate the @storybook/core package with storybook in a follow-up PR cc @ndelangen, which would clean up our code base quite a bit.

	Install size	Packages added	Lock file increase
storybook@~8.1	130M	596	5560 lines
storybook@~8.2	133M	470	4436 lines
toolbox split	72M	117	1186 lines
full CLI split (this PR)	63M	101	1071 lines
