Fix: Added build script to package.json to resolve frontend build errors

[priyanshscpp]

Description:
Previously, the npm run build command caused errors because the package.json file did not include a build script. This prevented the frontend from building and running properly.

The following changes were made:

Added a build script to package.json using Gulp.
The build process now works as expected, and the frontend can successfully compile and run.

Steps to Reproduce the Issue:

Before the fix, running npm run build resulted in the error: missing build script.
After the fix, the build process completes successfully using the Gulp task.

Testing Performed:

Verified that the npm run build command works without errors.
Confirmed that the frontend application compiles and runs as expected.
