Linear plugin

Files a Linear issue every time the classifier categorises a report.

Setup

1. Create a Linear API key → Settings → API → Personal API keys.
2. In Mushi: Marketplace → Linear → Install.
3. Provide:
   • apiKey — pasted into Vault, never echoed back
   • teamId — the Linear team to file under
   • labelMap (optional) — JSON object mapping taxonomy_path → label_id[]

Behaviour

• report.classified → creates a Linear issue with:
  • title = the report title
  • description = Markdown summary + report URL
  • priority = p0→1, p1→2, p2→3, p3→4
  • labels = labelMap[taxonomy_path] ?? []
• report.status_changed → resolved → moves the linked Linear issue to Done, leaving a comment with the merged PR URL.
