Let Claude CodeBuild and Test

Donobu is the testing browser for developers and coding assistants. It navigates flows, finds issues, and writes repeatable tests -- locally.

Claude Code updates the password validation rule (6 → 8) and calls Donobu via API to spin up a local browser test: 5 and 7 character passwords fail, 8 passes clean.
