feat: Add Google Apps Script compatibility runner

[chad-loder]

This adds a standalone Google Apps Script runner (tests/compat/gas-runner.gs) to test the native feature support of the GAS V8 runtime environment against the checks defined in tests/compat/tests.js.

Motivation:

Provide a way to easily check the native ES feature compatibility of the Google Apps Script environment, which is relevant for understanding potential polyfill needs when using core-js within GAS projects.

How it Works:

• The script is designed to be pasted into the script editor bound to a Google Sheet.
• It fetches a specific, commit-pinned version of tests/compat/tests.js from the core-js repository.
• It validates the fetched file's hash against an expected value.
• It modifies the fetched code slightly to ensure compatibility with the GAS execution environment.
• It evaluates the code and executes the test functions defined within it.
• It logs the results (pass/fail for each native feature check) to a new timestamped sheet within the active Google Sheet, applying conditional formatting for readability.

Usage:

Instructions for use are included in the comment header within the gas-runner.gs file.

Limitations:

• This script only tests the native environment's support for features checked by tests.js. It does not load or test the core-js polyfills themselves.
• It relies on the GAS environment having network access to raw.githubusercontent.com.

This runner can help generate compatibility data specific to the Google Apps Script platform.
