fix(napi/playground): only mangle if mangle option is enabled

fixes oxc-project/playground#160

[Copilot]

Pull Request Overview

This PR fixes a bug in the playground's minification logic where both compression and mangling were applied regardless of whether the mangle option was enabled. The fix ensures that compression and mangling are only applied when their respective options are enabled.

Key Changes:

• Restructured conditional logic to handle compression and mangling options separately
• Added early return when neither compression nor mangling are enabled
• Ensured minifier only applies transformations when explicitly requested
