ECMAScript Parser Test Runner

The `test262-parser-runner` is a utility designed to execute the official ECMAScript Test Suite (Test262) against any given JavaScript parser. Currently at version 0.5.0, it targets early-stage development and parser validation. While it doesn't specify a fixed release cadence, its versioning suggests ongoing development with potentially frequent updates. A key differentiator is its robust mechanism for managing test outcomes: it supports a `skip` filter function to completely ignore tests (e.g., for unimplemented features) and a `whitelist` array for tests expected to fail temporarily but eventually pass. This allows parser developers to precisely control which tests contribute to their pass/fail metrics. The project distinguishes itself by building upon a previously MIT-licensed test runner while distributing its own code under the GNU Affero General Public License v3.0, a significant detail for downstream users.
