Added madge as a verify check for circular dependency detection. Selecting it during verify init installs the package and wires up a verify:madge script. While integrating it I found and fixed a handful of actual circular dependencies — extracted shared types in the backlog web UI components and pulled common logic into a shared.ts module in the restructure planner.

Also added a /jira Claude command so Claude Code can fetch Jira issue context directly, and improved verify init to detect scripts already defined in assist.yml so it doesn’t offer to set up checks that are already configured. The init detection was refactored to pull setup handler registration into its own module and centralise the “install package and add script” pattern via setupVerifyRunEntry.
