Update to ES2026

[stonechoe]

What's Changed

• Bump submodule deps

  • ecma262 to tc39/ecma262@0248456
  • test262 to tc39/test262@f2d1435

• Updated the implementation to reflect recent editorial changes to the ECMAScript specification:

  • Added support for async built-in functions and methods.
  • Reflected the refactoring of anonymous built-in functions into abstract closures. (Note: the YetPath for anonymous built-ins also appears to be removable from ESMeta.)
  • Applied the updated Math notation introduced in Editorial: Introduce mathematical logarithm functions tc39/ecma262#3743 and removed the Log1p operator.

• Added Array.fromAsync, Error.isError, etc to the list of supported test262 features.

• Minor fix for type models
