robobun c7b9e0dc92 fix(node): prevent crash with null/undefined exports in process.dlopen (#24403) ...

## Summary

Fixes a segfault that occurred when calling `process.dlopen` with
`null`, `undefined`, or primitive values for `exports`.

Previously, this would cause a crash at address `0x00000000` in
`node_module_register` due to dereferencing an uninitialized
`strongExportsObject`.

## Changes

- Modified `src/bun.js/bindings/v8/node.cpp` to use JSC's `toObject()`
instead of manual type checking
- This matches Node.js `ToObject()` behavior:
  - Throws `TypeError` for `null`/`undefined`
  - Creates wrapper objects for primitives
  - Preserves existing objects

## Test Plan

Added `test/js/node/process/dlopen-non-object-exports.test.ts` with
three test cases:
- Null exports (should throw)
- Undefined exports (should throw)  
- Primitive exports (should create wrapper)

All tests pass with the fix.

## Related Issue

Fixes the first bug discovered in the segfault investigation.
