Pull request overview

Adds support for rewriting specifiers in calls made through require functions created via Node’s createRequire() factory, addressing #23.

Changes:

• Extend src/format.ts to track createRequire factories and the require-like aliases they create, so alias calls (and .resolve) are eligible for rewriting.
• Add a comprehensive test suite covering aliasing, renaming, reassignment, and shadowing scenarios for createRequire.
• Update README feature list and bump package version to 3.1.0.
