Pull request overview
Switches this repository’s automated dependency update mechanism from GitHub Dependabot (version updates) to Mend Renovate, aligning update grouping and branch targeting rules while enabling Renovate-native automerge/rebase behavior.
Changes:
- Add Renovate configuration under
.github/renovate.json(grouping npm + GitHub Actions updates, minor-only automerge, rebase-when-behind behavior). - Remove the existing
.github/dependabot.ymlto stop Dependabot version-update PRs.

| File | Description |

| .github/renovate.json | Introduces Renovate rules for base branches, grouping, minor-only automerge, and rebase behavior. |
| .github/dependabot.yml | Removes Dependabot version update configuration as part of the migration to Renovate. |

Replace dependabot.yml with a Renovate config that mirrors the existing rules (base branches, maintenance-branch restrictions, groupings) and adds what Dependabot could not do natively: auto-merge of minor updates once CI is green, and rebasing PRs whenever they fall behind the base branch. Commit type is pinned to chore(deps) so dependency bumps never trigger a semantic-release. Renovate runs as a GitHub App with its own push identity, so rebases re-trigger CI and merges fire downstream workflows (both impossible with the GITHUB_TOKEN-based workflow).

Switches dependency updates from Dependabot to Mend Renovate, mirroring the existing
dependabot.ymlrules and adding what Dependabot could not do with the defaultGITHUB_TOKEN:automerge: trueonmatchUpdateTypes: ["minor"]) — native, no branch protection or custom workflow needed.rebaseWhen: behind-base-branch) — rebases come from the Renovate App's own identity, so CI re-runs (aGITHUB_TOKENbranch update would not re-trigger workflows, and@dependabot rebaseis rejected from the Actions bot).Rule translation
