Tracking progress toward Guida v1.0 release

[decioferreira]

We’re working toward the initial release of Guida (v1.0).
This issue tracks the tasks we need to complete before cutting the release.

✅ Requirements for v1.0

• 📖 Finish the Guida website, especially documentation.
• move from elm references to guida #66
• 📦 Finalize the package registry:
  • Launch package.guida-lang.org
  • Support local deployment (for private libs, both Elm & Guida)
  • Ensure official registry only allows Guida packages (Elm libs go to Elm registry).
• 💻 Improve the VSCode extension (not necessarily feature-complete, but solid enough for v1.0).
• 🌐 Review client & browser support.
