Bug: The upgrade to Chai v6, an ESM-only library, is incompatible with the project's CommonJS test setup and will cause all tests to fail.
Severity: CRITICAL | Confidence: High

🔍 Detailed Analysis

The project is configured as a CommonJS module system, but the chai dependency is being upgraded to v6.2.2. This version of chai is ESM-only and does not support the CommonJS require() syntax used throughout the project's 36 test files. As a result, attempting to run the test suite will cause an ERR_REQUIRE_ESM error, leading to a complete failure of the test pipeline before any tests can be executed.

💡 Suggested Fix

Either revert the chai dependency to a v5.x version which supports CommonJS, or refactor the test suite to use ESM import syntax. The latter would also require adding "type": "module" to package.json or configuring the test runner for ES modules.
