renovatebot/renovate ? reverse-engineered prompt

Build me a dependency update tool that watches a code repo, finds package files automatically, checks for newer versions, and opens pull requests with the updates.

It should work across the big platforms like GitHub, GitLab, Bitbucket, and Azure DevOps, and handle common ecosystems like npm, Python, Java, .NET, Go, Docker, and other popular package managers. I want it to be configurable so teams can control when updates happen, how PRs are grouped, and which rules to follow.

Please make it able to work with private repositories and private registries too, and show useful details for each update like how old it is, how widely used it is, and how safe it seems to merge. If you need to, look up the current docs online so the setup and behavior match how Renovate is supposed to work today.
