This pull request introduces several improvements and fixes across the codebase to enhance maintainability, packaging, and user experience. The most significant changes include the addition of a custom after-pack script for Electron builds, improvements to accessibility and HTML structure, updates to dependencies and build scripts, and consistent formatting and logging. Below are the most important changes grouped by theme:

Build and Packaging Improvements

• Added a custom afterPack script (build-scripts/afterPack.cjs) to ensure all necessary files and directories (including assets, models, webfonts, and node_modules) are properly copied into the Electron app bundle during packaging. This improves reliability of packaged builds.
• Updated .prettierignore to exclude build artifacts and large directories from formatting, reducing unnecessary processing.
• Enhanced package.json build configuration: added new scripts for formatting and Windows build preparation, updated dependency versions, and improved build output and file inclusion/exclusion rules for cleaner distribution.

Accessibility and HTML/CSS Enhancements

• Improved index.html accessibility by adding appropriate lang attributes, meta tags, and visually hidden labels for form controls. Also refactored structure and classes for clarity and maintainability. [1] [2] [3] [4] [5]

Dependency and Code Modernization

• Updated key dependencies (mammoth, docx, pdf-parse, electron, electron-builder) to more recent versions for better compatibility and security.
• Refactored fileProcessor.js to use createRequire for importing CommonJS modules (like pdf-parse) in an ES module environment, improving compatibility.

Code Consistency and Logging

• Standardized logging messages throughout fileProcessor.js, main.js, and renderer.js for clearer, more consistent output and easier debugging. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14]

Documentation

• Updated README.md for clarity in installation steps and added minor formatting improvements for easier onboarding. [1] [2]
