fix(jest-util): prevent infinite recursion when writing to soft-deleted data property

[jon-zawada]

Summary

Fixes #16044.

When globalsCleanup: 'soft' is enabled, Jest replaces globals set between test files with accessor properties that emit a deprecation warning on access. For data properties the fallback setter was:

descriptor.set ?? (value => Reflect.set(obj, key, value))

After the property is redefined as an accessor, Reflect.set re-invokes that same setter → infinite recursion → RangeError: Maximum call stack size exceeded. Any project using globalsCleanup: 'soft' that re-assigns a global from a previous test file would hit this.

The fix introduces a closure variable (storedValue) that the getter reads from and the setter writes to directly, with no Reflect.set involved:

  let storedValue = descriptor.value;
  const originalGetter = descriptor.get ?? (() => storedValue);
  const originalSetter = descriptor.set ?? (value => { storedValue = value; });

This also fixes a secondary issue where the getter would always return the value captured at deletion time even after a successful write.

Test plan

Two new tests added to packages/jest-util/src/tests/garbage-collection-utils.test.ts:

yarn jest packages/jest-util/src/__tests__/garbage-collection-utils.test.ts

Tests: 3 passed, 3 total

• "does not recurse infinitely when writing to a soft-deleted data property" — would have thrown RangeError before the fix
• "reflects the updated value after writing to a soft-deleted data property" — verifies the written value is readable back after the write
