feat(detect-lang): add extra languages and extensions for lang detect

[georgeh0]

fixes #1163

[Copilot]

Pull Request Overview

This PR significantly expands the language detection capabilities by adding support for many more programming languages and file extensions. The refactoring changes the internal structure from a function-based approach to a more efficient static initialization pattern.

Key Changes:

• Refactored language registration from function calls to inline closure-based initialization
• Expanded support from ~20 languages to 100+ languages including ActionScript, Ada, Astro, Cairo, Elixir, Haskell, and many others
• Added comprehensive file extension mappings for existing and new languages (e.g., JavaScript now supports 25+ extensions)
