• Verify that moving 'apache-arrow' and adding 'shiki' to peerDependencies (instead of devDependencies) is intentional and aligns with the usage within the package.

        "apache-arrow": "19.0.1",

• Ensure that 'tsFile' is an absolute path as returned by glob and that extractTypeReferences handles absolute paths as expected.

                    const typeRefs = extractTypeReferences(tsFile);
