femanager.min.js breaks if bundled because not valid ESM code

[PARSE_ERROR] Error: Cannot assign to 'arguments' in strict mode

• in vendor/in2code/femanager/Resources/Public/JavaScript/Femanager.min.js at 658..667

Vite re-bundles it as ESM, which is always strict mode by spec.
So lets fix it: arguments is used as a local variable but also appears as a string literal in r.match("arguments") — so a blanket replace would break that. Lets use targeted replacements for each non-string occurrence.
Snippet from my vite.config.ts that documents the patch-on-the-fly needed:

        // 'arguments' is reserved in strict mode; rename the local variable usages
        // (keep the string literal r.match("arguments") untouched)
        return code
          .replace('arguments=JSON.parse', '_args=JSON.parse')
          .replace('for(var r in arguments)', 'for(let r in _args)')
          .replace('arguments.hasOwnProperty(r)', '_args.hasOwnProperty(r)')
          .replace('arguments[r]', '_args[r]');

The final config now patches both files surgically — replacing only the variable references to arguments, leaving the r.match("arguments") string literal intact.
Sorry for not offering a pull request, but in the package, there is only the dist version of Femanager.js, not the src version
