Pull request overview

Upgrades the project’s testing assertion stack from Chai v4 to Chai v5 (and aligns sinon-chai accordingly), updating the small number of required import interop points and refreshing the lockfile.

Changes:

• Bump chai to ^5.3.3 and sinon-chai to ^4.0.1, and remove now-unneeded @types/chai / @types/sinon-chai direct devDependencies.
• Update sinon-chai registration to use the default export (require('sinon-chai').default) in the test runner addon and the Kerberos manual test.
• Make dependency test cleanup more resilient by adding maxRetries to fs.rmSync when removing node_modules.
