.apply()/.call() on stdlib namespace methods returns undefined (path.join.apply, etc.)

[proggeramlug]

Summary

Calling a stdlib namespace method indirectly via .apply() / .call() returns undefined instead of dispatching to the native implementation. The method value reports as a function, but indirect invocation doesn't reach the native impl.

Discovered by the #800 node-core radar (e.g. test-path-join.js uses path.join.apply(...)).

Repro

const path = require('path');
console.log(typeof path.join);              // Perry: "function"  ✓
console.log(path.join.apply(null, ['a', 'b']));  // Perry: undefined   Node: "a/b"

Expected / Actual

• Node: path.join.apply(null, ['a','b']) === "a/b".
• Perry: typeof path.join === "function" but .apply() returns undefined.

Likely cause

Perry's stdlib namespace methods are dispatched specially; the function value exists (so typeof is correct) but it isn't a real callable that routes Function.prototype.apply/call back to the native method. Direct calls (path.join('a','b')) work; .apply/.call (and presumably passing the method as a callback) do not.

Context: surfaced running Node's own test/parallel under Perry (#800).
