Feature Request: Minify and Inline Nested Function Calls

Input Code

const profile = (_s, fn) => {
  return fn();
};

profile("trace1", () => {
  someFunction({
    args1: profile("trace2", () => JSON.stringify(someObj)), // if this line removed, the issue will not reproduce
    args2: JSON.stringify(someObj),
  })
});

Desired Output

someFunction({
    args1: JSON.stringify(someObj),
    args2: JSON.stringify(someObj)
});

Actual Output

const s = (s, r)=>r();
s("trace1", ()=>{
    someFunction({
        args1: s("trace2", ()=>JSON.stringify(someObj)),
        args2: JSON.stringify(someObj)
    });
});

Summary

Currently, swc does not fully inline and minify code when there are nested calls to a function. It appears that the nested invocation prevents successful inlining, so the minified output still contains the wrapper function. Ideally, the minifier should be able to inline these nested calls when their result is statically determinable and remove the wrappers, resulting in cleaner output.

Additional context

It seems that the bug or limitation is caused by nested calls to the profiling function. If the inner profile call is removed, inlining works as expected. Please investigate improvements to the minifier so that it can handle such nested patterns.
