Updated docs to point to the current profile.ts source after renaming a JavaScript file to TypeScript, ensuring accuracy and reducing user confusion.

April 2025: Key refactors and environment enhancements that improve maintainability, cross-OS developer experience, and documentation workflow. Hydro project codebase refactor increased readability and maintainability by standardizing generic naming and applying where clauses in trait and function definitions. CatColab dev environment now supports macOS and Linux via Nix-based devShells, with a refactored Nix config and package management for fswatch and TeXLive to streamline documentation generation. No critical bug fixes were required this month; the work delivered accelerates onboarding, reduces setup time, and strengthens the foundation for scalable future work.
