Generate a Mermaid flowchart centred on a single Jira ticket. Fetches the ticket's subtasks, parent, issue links, and recent comments in one call. The focal ticket is highlighted in indigo; subtasks are grouped in a subgraph; issue links use colour-coded arrows (red thick = blocks, cyan dashed = rel
