- projectGroupId: auto-detected from group chat context
- role: inferred from issue label (To Do/To Improve → dev, To Test → qa)
- model: detected from tier labels on issue, then falls back to heuristics
- issueId: if omitted, picks next by priority (To Improve > To Test > To Do)
All parameters are now optional. Tool includes autoDetected object in response
to indicate which values were auto-detected vs explicitly provided.
