Enterprise connector for teams that still live in Jira. Link Hollahoop posts to Jira issues, optional create Jira issue, Jira Done resolution -> Hollahoop Shipped, project/version reflection as roadmap badges. Supports Jira Cloud first; Data Center later if enterprise demand appears.

This is intentionally later than GitHub/Linear because Jira auth and field customization are messy. Build on the same integration-link abstraction so Jira does not infect core product vocabulary with epic/story/ticket terminology.
