feat(js): arrange babel plugins respectfully to vue and svetle frameworks

[e11sy]

Problems

• Framework files like .vue or .svelte are parsed with babel without jsx plugin that leads to this kind of errors

- JSX syntax inside of the `.js` files is not covered (leads to the same error above), however esbuild could build `.js` files with jsx plugin

Solution

• now files that do not have typescript enabled (like .js or framework files e.g. .vue without <script lang=ts> ) are parsed with jsx plugin

Note

We cant really enabled jsx plugin for all files because it collides with typescript plugin (<string>bar casts are treated as html tags etc)

• moved getPlugins function to utils and covered with tests separately
• added context of project / sourceMap frames to hawk catcher send method

Pull request overview

This PR fixes Babel parser configuration for Vue and Svelte framework files by properly handling JSX syntax and enabling TypeScript detection based on script tag attributes. The changes enable correct parsing of framework files and JavaScript files that contain JSX syntax, which previously failed due to missing parser plugins.

Key Changes

• Extracted and refactored Babel parser plugin selection logic into a testable utility function with comprehensive test coverage
• Implemented framework file preprocessing to extract script blocks and detect TypeScript language attribute from Vue/Svelte components
• Enhanced HawkCatcher error reporting with additional context (source code, line numbers, stack frames) for better debugging
