⚡ Bolt: [performance improvement]

[aafre]

💡 What:
Refactored the sequential for...of loop in exportIconsForYAML (in resume-builder-ui/src/hooks/useIconRegistry.ts) into a concurrent Promise.all map.

🎯 Why:
Previously, the fileToBase64 function (which utilizes FileReader to read files into base64 data URLs) was awaited sequentially. For large icon sets, this blocked the loop unnecessarily. These independent asynchronous file conversions are I/O bound tasks and benefit heavily from parallel execution.

📊 Impact:
Significantly reduces the overall time it takes to export icons, especially when many icons are stored in the registry, by executing the conversions concurrently instead of one by one.

🔬 Measurement:
Run pnpm test src/__tests__/IconListSection.test.tsx (or an end-to-end flow involving exporting icons/resumes) to ensure the export functionality remains intact without regressions.

Code Review

This pull request optimizes the icon export process in useIconRegistry.ts by refactoring a sequential await loop into a concurrent operation using Promise.all. This change parallelizes file conversions to improve performance. Additionally, a new learning entry was added to .jules/bolt.md documenting this pattern. Feedback was provided to refine the code comments by removing tool-specific branding and reducing verbosity while maintaining the explanation of the rationale and error handling strategy.

[gemini-code-assist]

The comment added here includes tool-specific branding ('⚡ Bolt') and is quite verbose, describing implementation details that are already evident from the code. It is better to use a concise comment that explains the rationale (parallelizing I/O for performance) and the error handling strategy without including meta-information about the tool used for the refactor.

Suggested change

	// ⚡ Bolt Performance Optimization:
	// Refactored sequential await loop for independent file conversions into a concurrent Promise.all map.
	// This parallelizes I/O operations and significantly reduces the overall export time.
	// Parallelize file conversions to improve performance for large icon sets.
	// Individual try/catch blocks ensure that one failing conversion doesn't abort the entire export.
