refactor(paragraph): extract paragraph block tool into standalone package

Move the built-in Paragraph block tool out of core into its own
publishable package, @editorjs/paragraph, versioned independently
like sdk, model and dom-adapters.

The source has no relative imports into core internals, so this is
a plain relocation — core now depends on it as a workspace package.
