Hi @drodil, haven't done a full review but see a couple of issues across the PR:

• New files should use the current year in the header
• Removed the jenkins: prefix as that's done automatically: https://backstage.io/docs/ai/mcp-actions#namespaced-tool-names

Pull request overview

This PR adds Jenkins “actions” registrations to the jenkins-backend plugin, exposing build listing, inspection, log retrieval, and build replay capabilities through the Actions registry (for MCP/scaffolder use-cases).

Changes:

• Register an actionsRegistry dependency in the Jenkins backend plugin and register Jenkins build actions during plugin init.
• Add four new Jenkins build actions (list-builds, get-build, get-build-logs, trigger-build) plus unit tests.
• Add a changeset describing the patch release.
