chore(ci) - add renovate

[gabrielseco]

Note

Low Risk
Low risk: adds a renovate.json config file only; it affects dependency update automation but does not change runtime code paths.

Overview
Adds renovate.json to enable Renovate with the recommended preset and turn on vulnerability alerts (ungrouped) for automated dependency update PRs.
