feat: convert package to pure Dart

[ricardodalarme]

Description

Hey @master-wayne7 👋🏻, thanks for this great package!

I noticed the Flutter dependency was only there to load the .txt word lists, , so I'm proposing this PR to change it to load the words directly from Dart files instead. This lets us drop the async initialization and turn safe_text into a fully pure-Dart project

A nice side effect: the word lists are now tree-shakeable, so you only ship the languages you actually use.

	JS bundle
All languages bundled	~1.4 MB
Tree-shaken (English only)	~322 KB

We're planning to use this in a large codebase here at VGV, and a Dart-only, tree-shakeable dependency makes that a lot simpler. I'd appreciate it if you could take a look 🙂

Hey @ricardodalarme , this is awesome, thank you! 🎉

Really appreciate the work here: dropping the Flutter dependency and making the word lists tree-shakeable is a great improvement, and the test coverage plus the data cleanup along the way shows real care. Everything checks out on CI.

Great to hear VGV is planning to build on this, very cool to hear as a maintainer. Merging this as v3.0.0 since it's a breaking change (sync API). Thanks again for such a solid contribution! 🙌
