Code Review
This pull request attempts to add a cooldown configuration to Dependabot updates for both github-actions and gradle ecosystems. However, as pointed out in the review, the cooldown option is not supported by the official Dependabot schema and will cause syntax errors, preventing Dependabot from running. These invalid configuration blocks should be removed.
Important
The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
