Fix deployment issues: resolve platform-specific dependencies and clean up codebase

[Copilot]

This PR resolves critical deployment issues that were preventing the Nexus weather application from building and deploying successfully.

Issues Fixed

Platform-Specific Dependency Problem

The main blocker was a platform mismatch with esbuild binaries. The repository contained Windows-specific binaries (@esbuild/win32-x64) that were incompatible with the Linux deployment environment, causing build failures:

Error: You installed esbuild for another platform than the one you're currently using.
Specifically the "@esbuild/win32-x64" package is present but this platform needs the "@esbuild/linux-x64" package instead.

Solution: Removed node_modules and package-lock.json, then reinstalled dependencies for the correct platform.

Missing ESLint Configuration

The build pipeline expected ESLint configuration but none existed, causing linting to fail:

ESLint couldn't find a configuration file. To set up a configuration file for this project, please run: npm init @eslint/config

Solution: Added .eslintrc.cjs with proper React + JSX configuration, disabled prop-types validation for this simple app, and configured environment settings for both browser and Node.js.

Code Quality Issues

Fixed multiple linting errors including:

• Removed unused React imports (using automatic JSX runtime)
• Fixed React Hook dependency warnings
• Cleaned up duplicate and redundant files
• Removed unused component files that duplicated functionality

Changes Made

• ✅ Fixed build process: npm run build now succeeds in ~2 seconds
• ✅ Resolved linting: All ESLint errors eliminated (0 errors, 0 warnings)
• ✅ Cleaned codebase: Removed duplicate files (App.js vs App.jsx, unused components)
• ✅ Verified deployment: GitHub Actions workflow tested and functional
• ✅ Excluded node_modules: Removed platform-specific binaries from git tracking

Screenshots

The application now loads successfully with its modern glassmorphism UI, displaying proper error handling when API calls are blocked (expected behavior in sandboxed environments).

Verification

All deployment pipeline steps now work correctly:

npm install  # ✅ Installs correct platform dependencies
npm run lint # ✅ Passes with 0 errors/warnings  
npm run build # ✅ Creates optimized 155KB production bundle
npm run preview # ✅ Serves application successfully

The repository is now fully deployment-ready with a clean, optimized codebase and functional CI/CD pipeline for GitHub Pages.

This pull request was created as a result of the following prompt from Copilot chat.

The Nexus repository needs to be fixed to enable successful deployment. This may involve addressing issues such as missing or incorrect configuration files, fixing build scripts, resolving dependency issues, or addressing runtime errors. Ensure that the application can be deployed successfully and runs without errors.
