Incorrect script command for `premev` in `package.json`

[ShahAnuj2610]

Description

The premev script in the package.json currently uses npx build, which causes an error because npx cannot find a command named build.

The correct script should use pnpm run build to execute the build script defined in the package.json.

Steps to Reproduce

1. Clone the repository.
2. Run pnpm mev init in the terminal.
3. Observe the error: npm ERR! could not determine executable to run.

Suggested Fix

Update the premev script in package.json to:

"premev": "pnpm run build"
